The length of regular expressions is limited in MV3, which is the latest iteration of the Chrome extension platform. (The Dynatrace Synthetic Recorder is a Google Chrome browser extension.) As a result, the length of URLs or match patterns you specify in browser monitor configuration to Block specific requests cannot exceed 90 characters. If your current string exceeds 90 characters:

  • The Block specific requests setting is not applied and needs to be fixed to meet the 90-character limit.
  • You will not be able to save certain changes to browser monitor configuration such as adding a request or validation. You can, however, change monitor name, frequency, outage handling, and thresholds. The Block specific requests setting needs to be fixed before you can save all changes.

Read more about this setting in Configure browser monitors.
