@dosubot[bot] commented on GitHub (Mar 27, 2025):

The error message "Expecting ',' delimiter" typically indicates a syntax issue in the JSON structure. In the provided input, it seems like there are two separate JSON objects without a delimiter between them. JSON requires a single root element, so having two separate objects without a surrounding array or object is invalid.

To resolve this, you can either:

  1. Combine the two JSON objects into a single object if they are meant to be part of the same data structure.
  2. Wrap the two objects in an array if they are meant to be separate but part of a collection.

Here's an example of how you might wrap them in an array:

[
  {
    "query": "6000"
  },
  {
    "sys.query": "6000",
    "sys.files": [],
    "sys.conversation_id": "d0bf8bcd-addc-424f-90fa-8107cbe662bc",
    "sys.user_id": "1893923125386395649",
    "sys.dialogue_count": 5,
    "sys.app_id": "0ce333d5-792d-43d7-a1be-318f52dea847",
    "sys.workflow_id": "67249da9-3401-45f1-beb5-60c14e379ca4",
    "sys.workflow_run_id": "8c2029af-f2c6-4a48-8acd-cd8b99f53e67"
  }
]

Ensure that the JSON structure matches the expected format for the classification node in Dify. If the node expects a specific structure, you may need to adjust the JSON accordingly.

It's quite strange. The same workflow can work normally sometimes, and sometimes not normally.

Hi, @zbximo. I'm Dosu, and I'm helping the Dify team manage their backlog. I'm marking this issue as stale.

Issue Summary

  • Reported bug in Dify version 0.15.3 related to a classification node in a Docker setup.
  • Error involves an invalid JSON object, initially thought to be a syntax error.
  • You and xpsky202 clarified the issue stems from Dify's source code, not user input.
  • JustLikeThis101 noted a similar issue with the Google search plugin in version 1.1.3, which resolves when the plugin is disabled.

Next Steps

  • Please confirm if this issue is still relevant to the latest version of Dify. If so, you can keep the discussion open by commenting here.
  • If there is no further activity, the issue will be automatically closed in 15 days.

Thank you for your understanding and contribution!
