Data Source REST Import not working because of File Extension Restriction

[Sebastian R_]

We are using a data source with Type REST (IntegrationHub) which retrieves the data via xml.

During our setup for the Instance Hardening (Instance Security Center) we modified the allowed extensions for attachments (glide.attachment.extensions).

Now the data source is not working anymore and the IH Step returns the following error:

Error encountered while creating Attachment. Error creating Attachment rest_action_response_body : Method failed: (/api/now/hub/temporaryattachment) with code: 400

Operation(Test Action Get.d61f2c951b10a0106da0bb31dd4bcbfc) failed with error: com.snc.process_flow.exception.OpException: Error encountered while creating Attachment. Error creating Attachment rest_action_response_body : Method failed: (/api/now/hub/temporaryattachment) with code: 400

The problem is obviously because the tempory file is called "rest_action_response_body" without an extension.

Has anyone faced the same problem and got a solutions for it? (Except clearing the property)

[Sebastian R_]

Thanks Robert.

We will then upgrade to Patch 5.
