ID 594881 - The /sbp endpoint can be blocked by Fastly WAF

Follow

Problem summary:
The /sbp endpoint can be blocked by Fastly WAF

 

Customer reported version:
Flix 7.0.2

 

Customer reported platform:
macOS 15

 

Steps to reproduce:
1) Start the Flix Server in an environment utilizing Fastly Web Application Firewall
2) In the Flix Client, attempt to import the attached sbp_that_fails.sbpz SBP project
3) Observe the 406 error that occurs:

[2025-02-06 15:51:31.997] [error] Http failure response for https://servername/show/36/sequence/1549/revision/0/reconform/sbp: 406 OK[2025-02-06 15:51:31.999] [error] HTTP failure, generic error

 

Expected behavior:
Storyboard Pro imports should succeed and not be flagged by Fastly WAF.

 

Actual behavior:
Some SBP imports are deemed suspicious and blocked by Fastly WAF, seemingly related to the file size of the SBP project.

 

Workaround:
Besides disabling the Fastly WAF, there is no known workaround at this time.
