Issue Description

While building a workflow, I added the following nodes:

  1. Start Node: Used to input a question.
  2. Knowledge Base Node: Receives the input question and generates corresponding data.
  3. JSON Conversion Node: Converts the data generated by the Knowledge Base Node into JSON format.
  4. End Node: Receives the converted JSON data and ends the workflow.

However, when configuring the JSON Conversion Node, I am unable to select the Knowledge Base Node as its input node. This prevents the workflow from executing properly.

Expected Behavior

I expect to be able to use the output of the Knowledge Base Node as the input for the JSON Conversion Node, so that the data can be successfully converted to JSON format and the workflow can proceed.

Actual Behavior

When setting up the JSON Conversion Node, the Knowledge Base Node does not appear in the list of available input nodes, making it impossible to establish the connection.

✔️ Expected Behavior

No response

❌ Actual Behavior

No response
