This issue was not reproducible. Please check that your example runs locally and the following:

• Ensure the script does not rely on dependencies outside of puppeteer and puppeteer-core.
• Ensure the error string is just the error message.

  • Bad:

    Error: something went wrong
      at Object.<anonymous> (/Users/username/repository/script.js:2:1)
      at Module._compile (node:internal/modules/cjs/loader:1159:14)
      at Module._extensions..js (node:internal/modules/cjs/loader:1213:10)
      at Module.load (node:internal/modules/cjs/loader:1037:32)
      at Module._load (node:internal/modules/cjs/loader:878:12)
      at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:81:12)
      at node:internal/main/run_main_module:23:47

  • Good: Error: something went wrong.

• Ensure your configuration file (if applicable) is valid.
• If the issue is flaky (does not reproduce all the time), make sure 'Flaky' is checked.
• If the issue is not expected to error, make sure to write 'no error'.

Once the above checks are satisfied, please edit your issue with the changes and we will
try to reproduce the bug again.

@Lightning00Blade can you please have a look? It seems that with 443ee99 not all issues with the rxjs import have been fixed.

This is a regression in the 21.5.0 release and everything was working fine with BiDi in 21.4.1.
