As of 9/1 we’re seeing a sudden large volume of bad records with the error:
Field [vid]: cannot convert [NaN] to Int
I believe this is the domain_sessionidx value?
We are still using JS tracker v2.6.2, no change there. Was there a change in certain browser functionality on that date that might affect this value somehow? (Just a shot in the dark, I know this value is derived from the user cookie.) Any other ideas on how this value could come back NaN?
It’s not affecting all events, only <=10%.
I am also seeing
duid=value= in the same bad records, again suggesting a cookie parsing issue?
Any ideas or corroboration appreciated.
