✅ Thanks for catching this @mcodik and fixing it @zimeg!

🧠 We should do a quick pass to make sure that we're not using params anywhere else. Then we may want to bring out another Python SDK Beta release for folks.

@mwbrooks This is a good call. I'll take a pass at this before merging:

• assistant.threads.setStatus: 👁️‍🗨️ Updated in this PR!

python-slack-sdk/slack_sdk/web/client.py

Line 2077 in 262a7b9

returnself.api_call("assistant.threads.setStatus", params=kwargs)

• chat.appendStream:

python-slack-sdk/slack_sdk/web/client.py

Line 2635 in 262a7b9

returnself.api_call("chat.appendStream", json=kwargs)

• chat.startStream:

python-slack-sdk/slack_sdk/web/client.py

Line 2894 in 262a7b9

returnself.api_call("chat.startStream", json=kwargs)

• chat.stopStream:

python-slack-sdk/slack_sdk/web/client.py

Line 2920 in 262a7b9

returnself.api_call("chat.stopStream", json=kwargs)

📚 AFAICT other methods can require either params or json depending on the attributes accepted and the actual API handlers. I believe "json" is required when structured values - not "flat" top-level strings - are used here!
