Language Studio won't accept my Blob Storage account; weird <doctype html> error.

Question

Language Studio won't accept my Blob Storage account; weird <doctype html> error.

The A Man 96

Looks like some internal error.

Earlier, I was getting the "storage blob data contributor role required for Language Product and User" errors, but those I resolved. This one error has been since the begginning and won't resolve. Deleted the resource group and redid everything, and even waited many days, yet this error won't resolve.

For some context, I'm attempting to use the Translator service for document translation, to translate a document with a million words. Have tried all and Bing's translator engine is just the best.

This is the full error.

Hello, The A Man

It seems you're encountering an internal error while attempting to use the Translator service for document translation. The error message provided appears to be an HTML document linked to the Language Studio service.

To address this issue, consider the following steps.

Verify the status of the Translator service in the Azure portal to ensure it is functioning correctly without any interruptions.

Review the configuration settings of the Translator service, particularly the input document size and any specific prerequisites for translating a document of this scale.

Confirm that the necessary permissions and roles have been appropriately configured for the Translator service, allowing it to access and process the document for translation.

Hope these helps you. Thank you!

I can confirm that the Translator service is working perfectly.

Also, I'm using a much smaller 2-page docs file for testing. But the error doesn't let me even proceed to the "upload source doc" stage, and even if I click the "Next" button too fast and somehow reach the "upload source doc" step, the docs file doesn't upload to the blob storage and it notifies of some internal unknown error.

Btw, is it okay if to use "Cold" blob storage or might it be a problem? I did once retry with "Hot" storage too but didn't change anything.

Hello@The A Man

I understand you are experiencing difficulties with the Translator service while attempting to upload a two-page document for testing. Regarding your question about using "Cold" blob storage, it should not be a problem. As you mentioned, using "Hot" storage did not change anything, indicating the issue may not be related to the type of blob storage.

To investigate further, please provide the following details:

Ensure the document meets the requirements of the Translator service.

Double-check the permissions and settings of your blob storage account to ensure it is configured correctly for the Translator service.

If the issue persists, please provide the complete error screenshot.

Thank you!

Brother, I'd tried everything and had already given up and deleted the resources, but now that you ask, I went in again and recreated the Translator and Storage Account to take a screenshot, and indeed, still the same error.

[A couple days ago, I tried recreating all the resources in WestUS2, and even my closest region which supports Translator service, but for some weird reason, it couldn't create the Translator service in my region (Central India and West India). Not sure if it's significant. Nevermind.].

Hello @The A Man ,

You need to add https://language.cognitive.azure.com endpoint in CORS with below Allowed methods.

DELETE
GET
POST
OPTIONS
PUT

User's image

Note: Make sure you assigned Storage Blob Contributor role to yourself and translators managed identity. User's image

The above configuration should work, if any query let us know in comments or in private message.

If above given solution worked for you please do accept and give feedback by clicking on yes.

Thank you

Now I'm not getting the error in notifications "the storage account does not have the required permissions", but the long <doctype html> error still persists...

Here's my storage account overview. Do you see anything sus? Thank you so much for your time. Also, what region are you deploying the Translator and Storage Account in? [Me deploying in EastUS]. Also, do I need some Quota for these?

I'm trying to convert the most important book in the world into Hindi language... All existing translations are crap. Bing's Translator AI gives the most literal word-for-word translation. Please help, brother...

Hi The A Man,

Set Allowed and Exposed headers to *, Max age to 500 in CORS tab then try selecting after refreshing the page.

Thank you

After setting allowed and exposed headers to * and max-age to 500, still doesn't work... Refreshed the language studio (language.cognitive.azure.com) and re-selected the storage account, and still, the same <doctype html> error...

[EDIT: brother, it worked! I guess it takes a couple minutes for those settings to take effect or something. It's not giving that <doctype html> error anymore. I went ahead one more step and checked and indeed, I could upload my source document (2 page demo document) for translation (which, earlier, wasn't possible; it used to give "unknown error").

Thank you so so so much, brother. I had prayed so bad to God for this error to go. You're literally a godsent. Thank you so so much. I'm translating the KJV Bible btw (check out TruthIsChrist on Youtube). Existing translations are based on other modern versions, and all twist the wordings and meanings and break cross-references. Google translator is horrible; they trained it on random unfiltered internet dataset. Thank you so so much...].

[EDIT: even the translation job succeeded! The word document has the formatting and everything all preserved! OMG this is awesome! I can't thank you enough, brother... Love you; bye.].
