It looks the error is not in the aws provider nor in the sdk. It's in AWS api.
Despite what the documentation says, when you call DescribeService it does not return ServiceUrl as it's documented, however it does if you call ListServices.

[pabloB2sys]

What do you recomend me to do ?
Because I'm working with terraform and the code needs this information as an output.

[sgrilux]

I think this will take time. I am going to raise an issue in the SDK repo hoping this will passed along the teams and fix it.
In the meantime you can probably use a null_resource with local-exec provisioner to call ListService and filtering out with --query or jq.

[sgrilux]

After digging a bit more, it looks the problem occurs only if the service is deployed privately and not publicly accessible. However the console returns the Url in any case.

[pabloB2sys]

That is correct the amazon console returns the proper URL in both cases.
As a requirement we have to move the service to a private vpc and have problems with security groups and open ports

I worked around this by using the dns_target attribute of the aws_apprunner_custom_domain_association resource.
