Can't set the headers

[ghost]

Hey there,
Thank you for this image. It works great on desktop.
I am trying to use it on Google Cloud Run.
I deployed it after changing some of the environment variables and it was perfect.
It works perfectly on desktop. A screenshot from a Georgian language news channel OCR'ed perfectly. But there is an issue with the cloud version

I can't set the headers on the build that's uploaded to the cloud
For example I can't set the X-Tika-OCRLanguage header via postman. I can send the png file via binary (and not multiform) and it renders OCR on default languages which are eng+rus+ara. Please note that I have apt-get tesseract-oct-all on the dockerfile.

I only get this WARN in the logs section:
WARN Both org.apache.tika.server.resource.TikaResource#getHTML and org.apache.tika.server.resource.TikaResource#getText are equal candidates for handling the current request which can lead to unpredictable results

Do I need an extra Header to send to the Tika?

What do you think about this? This is a common problem in all the images I have came across in the wild.
Is this a CORS issue? Do you know a way to fix this? Maybe it requires a new config on the tika-config.template.xml?

Best,

Thank you for shareing your information.
I am not very familiar with the Google Cloud, so this is a general opinion.

It seems not a Tika-Server related issue. It seems you are using reverse proxy because accessing your app via HTTPS (Tika-Server itself does not support HTTPS).
So you should check your server configuration to passing headers. I think you are in the state shown in Fig2 right now.

Fig1. Good OCR with localhost Tika-Server

Fig2. Bad OCR with HTTPS reverse proxy and passing no headers

Fig3. Good OCR with HTTPS reverse proxy and passing all headers

Thank you very much for the reply.
I resolved the issue by adding to the last line of the entrypoint
--cors http://localhost:3000
for localhost, but anyone can modify it to where their request is sent from.

After adding the --cors whateverClient line to the entrypoint
It certainly works for string put requests to /language/string api

const axios = require ('axios');

const putRequestConfig = {headers: {
        'Accept': 'text/plain',
        'Connection': 'keep-alive'
      }};
    
const lang = await axios.put(
'https://tika-5ev2qfbmha-ew.a.run.app/language/string', 
"console log which language is this text?", //Any text to request
putRequestConfig)

      .then(res=> console.log('The language of this text is ', res.data))  // Response to request
      .catch(console.log('Put request cannot work because of CORS in docker server'))

But I couldn't manage to put or post any image or pdf yet.
I must be doing something wrong.. but what...
