HTTP request node not working as intended

[Affan-Iqbal-DA]

Describe the problem/error/question

Just yesterday, my automation was working, I updated it to a newer version and regret followed. The output which was previously TEXT had turned to HTML despite changing NOTHING.
I have a 2 part workflow, main and sub, the sub is returning the correct output, the HTTP request node receives the CORRECT OUTPUT (TEXT) and then outputs HTML instead of the TEXT as it previously did.

What is the error message (if any)?

No error message.

Please share your workflow/screenshots/recording

Please contact our host directly.”\n\n2.

I’m here to make your stay in Dubai as comfortable as possible!”\n\n4.

Please verify the name or contact our host.”\n\n"

Hey @Affan-Iqbal-DA,

Thank you for reaching out! We’ve received your issue and are looking into it. To help us track this internally, we’ve created a Linear ticket with the reference: "GHC-3277".

We’ll keep you updated as we make progress, but if you have any additional details or context to share, feel free to add them here - it’s always helpful!

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

[Affan-Iqbal-DA]

I have updated n8n once more a few moments ago so the problem is with the 2nd last update (stable one).
The problem is still there.

[juancamposlb]

it seems they have introduced this change
https://docs.n8n.io/release-notes/#webhook-html-responses

Is there a way to disable it, or go around it?

I see. While keeping the HTTP request node, I don't have an alternative way to output text but you can use "Execute a sub workflow" node but it has less flexibility.

[pipars]

Please help me to understand something. The change was introduced to "protect instance users". In case of self-hosted environment, what does it mean? I do appreciate the concern, but there should be more testing done and migration guide published before including it, becasue any html producing flows do not work anymore. So, now we trying to figure out what to do and all in the name of "for your safety"? is that correct?

I would like to have an option to disable it.

It can be disabled on self hosted only at the moment, It could be worth checking the node to see if it needs to return html or if you can just use plain text. If it is just test you may be able to work around it.

Same problem here. I am using a self-hosted instance. We need more time to migrate or at least a temporary alternative. Maybe having an env variable or a setting in the response node (like INSECURE HTML, disabled by default)

Can you explain, how to do it in self-hosted?
