My extension plugin runs normally on the cloud edition, but after installing it on the community edition, an error occurs when opening the settings. The error log is as follows:

Settings configured:
FORCE_VERIFYING_SIGNATURE=false
ENDPOINT_URL_TEMPLATE=https://domain.xxx/e/{hook_id}

LOG:

Hi @kevintsai1202,

Thanks for reporting this issue. Based on the error log, this appears to be an issue with the Dify main application or the plugin daemon, not the SDK itself.

The error PluginDaemonInternalServerError: failed to decrypt settings: data is nil indicates a problem with the endpoint settings encryption/decryption in the Dify backend.

This issue should be reported in the main Dify repository:

Please provide the following information when creating the issue there:

  1. Dify version
  2. Plugin daemon version
  3. Your plugin's manifest.yaml and endpoint configuration
  4. Steps to reproduce

Closing this issue as it's not related to the SDK. Thank you for your understanding!
