AWS CLI standard error format "An error occurred" error code message Botocore AWS service response ErrorMessage string contract

💡 Result:

For an AWS **service error**, Botocore’s `ClientError` formats the exception as:

```text
An error occurred (<Code>) when calling the <Operation> operation: <Message>
```

It reads `<Code>` and `<Message>` from `error_response["Error"]` (falling back to `Unknown` if either is absent). That is Botocore’s exception-message format; the AWS CLI writes errors to **stderr**, and its displayed format depends on `--cli-error-format`—the current docs describe `enhanced` as the default, with `legacy`, `json`, and other options available. ([github.com](https://github.com/boto/botocore/blob/develop/botocore/exceptions.py))

The relevant parsed response fields are `Error.Code` and `Error.Message`. They are **not a universal wire-level `ErrorMessage` string contract**: for JSON-protocol responses, Botocore accepts `message` or `Message`, and obtains the error code from `__type` (or falls back to the HTTP status code). ([github.com](https://github.com/boto/botocore/blob/develop/botocore/parsers.py))

So if you’re asking whether a service must return a literal `ErrorMessage` field for the CLI text to work: **no**. Botocore normalizes protocol-specific responses into `Error.Message` before `ClientError` formats them. The exact wire shape is service/protocol-specific; the cited Botocore parser is the current `develop` branch, not a pinned version. ([github.com](https://github.com/boto/botocore/blob/develop/botocore/parsers.py))

Match RepositoryNotFoundException in the error header.

Botocore formats the error code in the header and the service message after the colon. Because this grep scans all of stderr, a different error whose message contains (RepositoryNotFoundException) can be treated as already deleted. The mention fixture uses the token without parentheses, so it does not test this case.

🐛 Suggested fix 
-  if grep -q '(RepositoryNotFoundException)' "$DESCRIBE_ERR"; then
+  if grep -q '^An error occurred (RepositoryNotFoundException) when calling the DescribeRepositories operation:' "$DESCRIBE_ERR"; then
-        echo "An error occurred (AccessDeniedException) when calling the DescribeRepositories operation: not authorized; RepositoryNotFoundException is not the cause" >&2
+        echo "An error occurred (AccessDeniedException) when calling the DescribeRepositories operation: not authorized; (RepositoryNotFoundException) is not the cause" >&2

Review comment at @scripts/force-delete-owned-ecr-repo.sh at line 110:
Update the RepositoryNotFoundException check in the describe-repository error
handling to match the Botocore error header for the DescribeRepositories
operation, rather than matching that token anywhere in stderr. Preserve the
existing behavior for genuine not-found errors.
