@dosubot[bot] commented on GitHub (Sep 24, 2025):
The PluginInvokeError with "ValidationException: The provided model identifier is invalid" for Claude Opus 4.0/4.1 in Bedrock plugin 0.0.36 and 0.0.37 (with Cross-Region Inference enabled) is caused by stricter model identifier validation and changes in how model IDs are constructed in these plugin versions. The plugin now requires specific region-aware model ID formats (like
global.anthropic.claude-opus-4-20250514-v1:0) and a validinference_profile_idin the configuration. If the model ID or region mapping is incorrect, Bedrock returns this validation error. This stricter logic does not affect Sonnet models or plugin version 0.0.35, which is more permissive and works as a temporary workaround for Opus models details.To resolve or work around this:
inference_profile_idin your model configuration.This issue is actively tracked and discussed in the repository, and configuration or plugin updates may be needed for full compatibility with Opus 4.x models in future releases.
To reply, just mention @dosu.

@nadazero commented on GitHub (Sep 27, 2025):
The Model ID and inference profile ID are both generated by AWS and cannot be modified or customized by users.
So, how can users ensure that the model ID is correct or not?
Has an official DIFY staff member come forward to explain this issue?
The AI's answer seems reasonable, but there is no fundamental explanation for why the plugin is reporting this error now.
Is it possible that it is a bug in the program?
@nadazero commented on GitHub (Sep 27, 2025):
I asked AWS official customer service and received an answer that currently only the Claude Sonnet 4 model supports adding the global prefix in front, while Claude Opus 4.0/4.1 does not support the global prefix.
That's why the 0.0.36/0.037 plugin version reports Opus 4.0/4.1 works NG but Sonnet 4 works OK.
It is almost certain that this is a plugin bug.
At present, only Claude Sonnet 4 should be checked and Claude Opus 4.0/4.1 should not be checked.

We hope DIFY could fix this issue ASAP.
@nadazero commented on GitHub (Sep 27, 2025):
