I verified the attribute exists using the /data_attributes endpoint, but when I send a POST request to /conversations/search, I get:
{'type': 'error.list', 'request_id': '001ked9vudjnmtu2fm40', 'errors': {'code': 'invalid_field', 'message': 'custom_attributes.Details is not a valid search field'}]}
I am able to filter on built-in values, like "created_at" etc OK so the code works but the search query using custom_attributes, doesn't.
Anyone else have this same problem?
