@ONBOSS_DIGITAL You are trying to modify a field (most likely a dropdown field) which requires you to use a UUID or an orderindex instead of text.
ClickUp custom fields something requires this instead of text, so it gives you this error. You can find information about custom field with the module “Get custom fields”
I understand that you’re sharing this piece in a DM because it probably contains some sensitive info. Do you think you could post a short summary of the solution here as well, though, so that the rest of the community can also learn from you?
the issue is that the dropdown field options have two values in ClickUp i.e. Display Value and the Internal Code (Index or UUID) for that item.
In general, when we Map the option value from a previous module, it comes like a display value; however, in mapping, Clickup expect the internal code (Index or UUID). Hence due to this mismatch, it returns error 400 FIELD_011.
You can use the Switch module to convert your display value to Index or UUID and pass it to ClickUp.
Feel Free to reach out if you want to implement this in your scenario and fix it.
