  Hello Enrique,

  Yes, that’s correct, the version you were on is 4.8.20252.399, and the fix is available in the newer build 4.8.20261.413.

  Since the httpHandlers/httpModules entries reference the assembly with an explicit Version= attribute, you’ll need to update those entries to point to the new version after upgrading. The simplest approach is to replace 4.8.20252.399 with 4.8.20261.413 in each type= string (all three entries you pasted).

  It should continue to work without any changes after this update.

  After updating the version strings and rebuilding, please give it a try and let us know if you run into any issues. Please share images of the issue you get so that we can investigate accordingly.

  Regards,
  
  Uttkarsh.
