Changing the ServiceNow properties in this guide can break attaching files, uploading files, publish integrations, and more for the whole instance.
We highly recomend testing these changes first in a non-production environment.
We also highly recomend making a copy of the original values for each property you change, so if something does break you can revert your changes.
If you are unsure of any change please contact us https://runthru.com/AboutUs/ContactUs
Navigating to the System Properties List
Enter sys_properties.list in the filter field in the All menu and press enter
Attachment Extensions
Enter glide.attachment.extensions to the search field and press Enter
Click glide.attachment.extensions
If the Value is empty then go back to the System Properties list and skip the rest of this section and go to Specifying the MIME Type
Otherwise if there is content continue to the following step
Append ,rthru to the value field
Click Update
Option 1 (Recommended): Adding rthru MIME type
Make sure you are on the the System Properties page
Enter glide.security.mime_type.extension_mapping into the search field and press enter
Click glide.security.mime_type.extension_mapping
If the property glide.security.mime_type.extension_mapping does not exist, create it by clicking New
Make sure the type of the property is string
Add rthru=application/zip in the Value field
If there is already something in Value you should add a comma to the end of the existing line and the rthru value on a new line below
For example this value
example=application/zip
Should be turned into this
example=application/zip,
rthru=application/zip
Click Update
Option 2: Ignoring MIME Validation
