Summary
The javascript tracker release 2.9.1 wrongfully introduced additional feature flags (wheel and passive event listeners).
This change would trigger validation failures since those feature flags were not reflected in the associated schema.
Who is affected
You are affected by this issue if you’re using the javascript tracker version 2.9.1.
How to recover
You will need to reprocess the produced bad rows and remove the f_wheel and f_passive event properties.
How to avoid this issue
We have removed those feature flags from release 2.9.2 and, as a result, encourage people to upgrade to this version.
