Version Compatibility
Browserless workers are updated periodically with new browser and library versions. Matching your client library version to the versions running on our workers is important, especially for Playwright's connect method, which is tightly version-coupled. If your code is unexpectedly crashing, version mismatch is a common cause.

If your code is mysteriously crashing, try using the exact version mentioned above, as some older but especially more recent versions than the above may cause conflicts.
Playwright's versioning
Playwright's connect method is tightly version-coupled. Your client version must be one of the versions listed above.
Playwright's connectOverCDP does not always need to match the same Playwright version on our workers. This method is generally backwards/forwards compatible since it communicates directly through CDP, with the caveat of being slightly slower due to more communication over the DevTools protocol.
