Hi all 
,
We have an active Exalate connection syncing issues between a Jira instance and a ServiceNow instance.
We encountered an issue where an attachment fails MIME type validation on the ServiceNow side during sync, causing the following error:
“Response received from ServiceNow while Adding attachment [filename].txt with status 400: Message: Invalid file type: text/html, None”
The file has a .txt extension but is being identified as text/html by ServiceNow, which then rejects it. This appears to happen because ServiceNow inspects the actual file content rather than relying solely on the file extension (MIME type checking).
Disabling MIME type checking on ServiceNow is an option, but since its a global setting… i really don’t want to do that 
Has anyone run into this? Is there a recommended workaround or a way to handle this type of MIME validation error on the Exalate side?
Regards,
Theo.
