[Bug]: `HTTPException: 400: Object of type bytes is not JSON serializable` Error in Tasks with API Call Tools #655

Open HamadaSalhab opened 2 days ago

HamadaSalhab commented 2 days ago

📜 Description

Tasks that include a tool_call step of type api_call are throwing an HTTPException: 400: Object of type bytes is not JSON serializable error. This happens only on our dev server. I couldn't reproduce it locally (task ran fine locally).

👟 Reproduction steps

Run this task

name: Test Task

tools:
- name: api_tool_call
  type: api_call
  api_call:
    method: GET
    url: "https://jsonplaceholder.typicode.com/posts"

main:

- tool: api_tool_call

👍 Expected behavior

The task should perform the api call and successfully finish the execution.

👎 Actual Behavior with Screenshots

The task is stuck on init state, so there's no output from the tool_call step.

💻 Operating system
