Unknown error

[BrancoYuri]

Describe the problem/error/question

I have a flow that's being tested. I've probably run it over 100 times, and the nodes worked every time. It was a flow I imported from a template I downloaded, and it always worked.
It turns out that recently, after I updated the version on Railway, the hosting I use, it started displaying a very strange error (I don't believe this is the cause of the problem). This error initially occurred on an OpenAI "message a model" node, and the issue was resolved when I recreated the node, transferred the settings to the new node, and it worked.
After that, I ran the flow from scratch, and the create a file from Google Drive node started displaying the same error. What's even stranger is that after updating Railway, I had already run the flow at least 10 times, and all nodes were working. It only stopped on the OpenAI node. Then, only after I fixed the problem on the OpenAI node did the Google Drive node start showing the SAME error that had been showing on the OpenAI node.

The biggest problem is that even after recreating the Google Drive node and following the same procedure I did on the OpenAI node, the problem persists and returns with the same error. I even tried starting the flow from scratch to see if I could fix it, but it keeps giving the same error.

Oh, another detail: while I was writing this email, I noticed that practically ALL nodes are experiencing problems, except for the data processing nodes, IF, MERGE, SET, and CODE. There are other AI Agent nodes that I thought weren't having problems, but in reality, their Output is pinned, meaning it's not being executed. I'm sure that if I unpin this node, it will also cause problems. I know this because when I went to redo the workflow, these nodes gave problems because they weren't pinned.
I've already reverted to the previous version in Railway, hoping it would work, but it didn't.
I also just noticed that ALL my other workflows, which have always worked and which I've been creating for months, now have the SAME error.

What is the error message (if any)?

Your request is invalid or could not be processed by the service
column 9827483463398fbb7d6b96916fe451d8bdefa0e8.role does not exist
Error code: 42703

Please share your workflow/screenshots/recording

I took this second printout when I was creating the first report, which was closed because it was written in Portuguese.
Now, when I rewrote it in English, the error simply disappeared, and the old workflow returned to normal operation, without me having made any changes. However, the current workflow I'm working on continues with the same error.

The third print was taken now, exactly from the same node that was not working minutes ago and suddenly started working again

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)
⚠️ WARNING ⚠️ If you have sensitive data in your workflow (like API keys), please remove it before sharing.

"output": "A luz da lua filtrava-se através das copas das árvores em câmara lenta, como se a própria noite tivesse sido possuída por uma essência estranha. Naquele bosque isolado, onde o ar pulsava com um som suave e constante, o sussurro do vento era um convite para aquilo que não deveria ser encontrado. Clara sempre achara o local perfeito para suas escapadas da rotina insuportável da cidade. Contudo, naquela noite, algo estava péssimo.\n\nSentada numa pedra fria, ela notou pequenos movimentos no canto de sua visão — formas indistintas dançando nas sombras. Um calafrio percorreu sua espinha, mas seguiu observando. Objetos deixados para trás pela natureza pareciam agora formar padrões que burlavam sua compreensão. As folhas, ao invés de caírem, levitavam, como se uma força invisível as manipulasse. Um frio súbito inundou-lhe a mente, uma percepção de que não estava sozinha.\n\nA sensação de vigilância tornou-se palpável. Clara começou a visualizar silhuetas tortuosas que emergiam das árvores, mas mesmo faltando a luz, os contornos expunham-se a uma curva antinatural. “Ninguém mais está aqui”, pensou, enquanto o eco de seus próprios pensamentos reverberava como um alerta buscando abrigo. O medo tomou as rédeas, transformando-se em uma convulsão na certeza de que olhos iam muito além do que poderia ver.\n\nNaquele crepúsculo disforme, Clara não pôde evitar as vozes. Um sussurro colossal, uma comunicação que parecia vir de mil dimensões, um convite e uma maldição. Cada palavra era um abismo, levando-a a questionar a própria tessitura da realidade. Ao olhar para as sombras, uma vontade profunda enredou sua mente — o desejo de entender aquele desconhecido.\n\nEntão, ela viu. Uma forma enorme, um deslizar de texturas impossíveis que desafiava toda lógica — tentáculos, esferas e fractais que se contorciam em um balé grotesco. O que era aquele ser que flutuava entre as árvores? Aquilo não era um medo personificado; era a própria essência do terror cósmico, uma presença que desalinhava a compreensão humana. Havia um segredo ali, algo que lotava o universo de formas alienígenas.\n\nEnquanto a realidade se esvaía, Clara tentava gritar, mas apenas um sussurro hesitante emergiu de seus lábios. Ao final, a presença a envolveu, e a consciência da garota diluiu-se, perdida entre as nebulosas visões. No silêncio do bosque, o uivo da noite era a única resposta, ecoando a pergunta que nunca poderia ser feita: o que mais habita as sombras?"

Thanks for your patience and for bringing this to our attention.

Hey @BrancoYuri

We have seen this a few times recently, can you make sure that your workers are on the same version of n8n as your main instance.

[BrancoYuri]

I'm still getting familiar with n8n. I haven't used it for more than three months, so I'm not a very experienced person here.
I can't guarantee this, but I have a few questions, beyond the flow version and my main instance.

The flows always worked normally until I updated the Railway instance. So far, so good. It could indeed be something with the update, but that leads me to believe that's not the problem.
Even after updating the instance, the nodes continued to function normally. There was only one node with the issue I reported (message a model - OpenAI). The Google Drive nodes all worked, and the node version was the same before the update, version 3, and now they remain at that same version.

I recreated the problematic node (message a model - OpenAI), and it worked. But as soon as I did that, all the other nodes stopped working, giving the same error, and I hadn't made any other changes.

Even flows I hadn't changed had the same error.

After that, I reverted to the previous version of the instance, which in theory would solve the problems, since in that version all the nodes worked, but the errors persisted.

What puzzled me were these two issues I reported. The Google Drive nodes INITIALLY continued to work even after the update. They were run about 10 times after the update and worked, but then they suddenly stopped. The other thing that intrigued me was that even after I reverted the instance to the previous version, the problems remained. If it were a flow version issue with the instance, the problem would be resolved when I reverted to the version before the problems started.
Finally, any new flows I create with the "new" nodes present the same problem. Even if my old flows had the problem, if I created a new one, this failure shouldn't occur.

[BrancoYuri]

This morning, I started the flow from scratch. It seemed like everything would work, but when I got to the blessed Google Drive node, I got the same error. I didn't copy and paste the node from my old flow; I created a new one, which in theory should have worked, but it didn't. It gave the same error as before. I've attached the image.

[BrancoYuri]

Is there any news for today?

[BrancoYuri]

Well, it took me a while, but I managed to identify where this update should appear. I finally found it, and that was indeed the problem: the main instance version was updated, but the workers weren't.

Also, I found some information about variables. When simply updating the workers version doesn't work, it's worth trying the following variable:
Name: N8N_RUN_MIGRATIONS
Value: true
After that, you deploy it, and when you're done, you delete it and deploy it again. This worked in most cases where updating didn't solve the problem.
