Madhu Challapalli Thanks for posting your question in Microsoft Q&A. Quickly reviewing the correlation id, you shared, I found the following error message in the logs:

{"error":{"code":"InvalidParameterValueInContainerTemplate","message":"The following field(s) are either invalid or missing. Field 'template.containers.functions-container.image' is invalid with details: 'Invalid value: \"<xxx>.azurecr.io/sandbox/ctr-adr-egpoc:latest\": GET https:?scope=repository%3Asandbox%2Fctr-adr-egpoc%3Apull&service=<xxx>.azurecr.io: UNAUTHORIZED: authentication required, visit https://aka.ms/acr/authorization for more information.';."}}

From the error message, it looks like the field has invalid value or a private container registry missing the credentials for authentication.

Please validate the field value is correct (sample value for docker: DOCKER|myacr.azurecr.io/myimage:mytag from doc reference) and if it is private container registry, add three registry settings in your bicep template as described in doc: Application Configuration. User's image

I hope this helps and let me know if any questions.

If you found the answer to your question helpful, please take a moment to mark it as Yes for others to benefit from your experience. Or simply add a comment tagging me and would be happy to answer your questions.

Hello Muthu, Thanks for the response. I am still facing the error with func app even after passing config key but am able to deploy container app with the same keys.

Madhu Challapalli For the above correlation ID, I found different error message which indicates that registry server has invalid value for the function app. Please validate registry server value and if it is same as container app, then we might need to investigate further.

In that case, send an email to azcommunity@microsoft.com referencing this thread with subject as "Attn: Muthu". I will assist you offline.

Update for the community:

The second issue was resolved after changing DOCKER_REGISTRY_SERVER_URL value in the template from "https://test.azurecr.io" to "test.azurecr.io".
