This error may be specifically related to the email.send_email pack since when I comment it out, the workflow runs correctly. I'll try to get more information.

Sorry, I just realised that I didn't provide the full exception, the first exception was raised while processing another exception. The full trace is as follows:

ValueError: Failed to cast value "carlos@XXXXX" (type: str) for parameter "email_to" of type "array": malformed node or string: <_ast.BinOp object at 0x7f3a07b07b00>. Perhaps the value is of an invalid type?
The stack trace from the Action-Chain pin points the actual issue, which is an incorrect data type being provided to the action parameter.
From the action email.send_mail it is defined as an array type.
"email_to": {
"description": "Email addresses to send TO.",
"required": true,
"type": "array"
},
