It is possible to set up an automation rule to auto-route tickets based on file types, including HAR files. However, the feasibility and specific details of implementing such a rule may depend on the ticketing system or software that you are using.

If your ticketing system has the capability to detect file types of attachments, then it may be possible to set up a rule that triggers when a ticket is submitted with an attachment of there file type. The rule could then automatically route the ticket to a specific team or assignee based on your preferences.

However, if your ticketing system does not have this capability built-in, it may be necessary to explore other solutions, such as using a third-party integration or developing a custom script to accomplish the task. In either case, it's important to ensure that the solution is secure and compliant with any relevant data protection laws and regulations.

It's also important to keep in mind that automated routing based solely on file type may not always be the best solution for handling sensitive information. It may be helpful to consider additional measures, such as encryption or access controls, to protect the sensitive data within the HAR files.
