Airtable TypeCast Not Working

You are right, it is not scope related.

I saw another topic with this issue (Airtable Typecast is not working - #9 by peterng1618) and I think I understand what the problem is, it’s due to the node expecting a value in the options field.

To fix this on my workflow, I downloaded the workflow json, change the line related to my Select field from options to string and it works:
"type": "options", -> "type": "string",

I don’t know if my workaround makes sense? Maybe n8n has another way to do this?
