Custom Neural Model Training Always Fails: Content is not accessible Could not retrieve build data within 60 seconds.

My Goal: To train a custom Model using the Form Recognizer Studio.

No matter how I try to build a custom model (API, SKD, Form Recognizer Studio), it always fails with:

ContentSourceNotAccessible
Content is not accessible: Could not retrieve build data within 60 seconds.

and I have tried it over 20 times now.

Here are some Screenshots from the Studio:

and Via API:
Request:
{ "modelId": "TestModelName", "description": "Something", "buildMode": "neural", "azureBlobSource": { "containerUrl": "https://somestorage.blob.core.windows.net/somestorage", "prefix": "" }, "tags": { "createdBy": "Me" } }

Result in the Operation:
{ "operationId": "31517210447_ad4c457c-9a26-410b-b4b4-4d6cea9ddba1", "kind": "documentModelBuild", "status": "failed", "createdDateTime": "2022-04-05T11:19:12Z", "lastUpdatedDateTime": "2022-04-05T11:20:13Z", "resourceLocation": "https://francecentral.api.cognitive.microsoft.com/formrecognizer/documentModels/TestModelName?api-version=2022-01-30-preview", "percentCompleted": 100, "error": { "code": "InvalidRequest", "message": "Invalid request.", "details": [ { "code": "ContentSourceNotAccessible", "message": "Content is not accessible: Could not retrieve build data within 60 seconds." } ] }, "tags": { "createdBy": "Me" } }

    Hi, thanks for reaching out. From the error message, I'd assume the issue has to do with accessing your files from blob storage. However, the above image shows the files loaded in the portal. I also tried to train a custom neural model and it ran successfully. It's unclear what exactly is implied by the error message. These are my recommendation: review the following document, ensure that your resource is in the supported regions list and that none of the limitations apply, and ensure that your input data follows the input requirements. Hope it helps.
