Your translator resource must have "Storage Blob Data Contributor" role in the Azure Blob storage account to run document translation jobs

Hi, I also had this problem and managed to solve it. Storage Blob Data Contributor role must be assigned on the translator resource by manage identity and on the user who runs Language Studio applications.

The permission assignment should be done at the container level within your Azure Blob Storage to ensure that the Translator has the necessary permissions to read, write, and delete blobs and additionally when using the managed identity with Azure RBAC, do not use SAS tokens in your requests. Instead, use the plain storage account URLs, as the managed identity provides the necessary authentication.

i have some troubleshooting linked those may help you

Hello Jonah Munholland,

Greetings Welcome to Microsoft Q&A Platform.

I understand that you are facing issues while selecting Azure Blob storage account when using the translator tool in language studio and getting following error {Your translator resource must have "Storage Blob Data Contributor" role in the Azure Blob storage account to run document translation jobs}.

Sometimes, the Storage Blob Data Contributor role alone might not be sufficient. You might also need to assign the Reader role to navigate through the Azure portal. Also check if the user has necessary permission to access the data as Managed identities for Azure resources are service principals that create a Microsoft Entra identity and specific permissions for Azure managed resources.

Following doc will help you setting up the translator - https://techcommunity.microsoft.com/t5/ai-azure-ai-services-blog/document-translation-now-available-in-the-language-studio/ba-p/3825711.
