I also encountered the same error. I resolved it by doing this:

  1. find you model id and Inference profiles ID in bedrock
  2. add a new model from bedrock dify plugin
  3. filled with your model id , Inference profiles ID, access key id, secret access key

it seems that if your model not support cross-region inference can not be added successfully.

@mofee / @tang2554 can you check with latest plugin 0.0.30 to see if it resolve your issue?

@natsumechan commented on GitHub (Aug 19, 2025):

I’m encountering the same issue.

When an Agent uses the Redmine plugin together with Amazon Bedrock, executions fail intermittently. Some runs succeed, while others return errors.

Steps to reproduce

Create an Agent.

Add the Redmine plugin as a tool.

Run the Agent multiple times.

After several runs, errors occur at random rather than under specific, repeatable conditions.

Expected behavior

The Agent should consistently invoke the Redmine plugin in response to input and return a normal result without errors.

Actual behavior

Agent executions fail sporadically and return an error message.

Environment

Dify: 1.7.1

bedrock plugin: 0.0.31

Deployment: Self-hosted (Docker)

Hi, @wcbwing1. I'm Dosu, and I'm helping the dify-official-plugins team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You reported a PluginInvokeError about a missing model name when integrating Bedrock in a workflow on Dify 1.7.1 with plugin 0.0.27 in a self-hosted Docker setup.
  • Bedrock works fine as a single agent, but the error occurs in workflows.
  • Other users confirmed the same error, with a suggested workaround to manually add the model with correct IDs and credentials.
  • The maintainer recommended upgrading to plugin version 0.0.30 or later.
  • Additional reports indicated intermittent failures when using Bedrock alongside other plugins in later versions.

Next Steps:

  • Please confirm if this issue is still relevant with the latest version of the dify-official-plugins repository; if so, you can keep the discussion open by commenting here.
  • Otherwise, I will automatically close this issue in 5 days.

Thanks for your understanding and contribution!
