Hi @tecbot, can you provide a minimal sample? Can you also check if it reproduces on the latest version of cloud_firestore?

[tecbot]

@danagbemava-nc I can't create a minimal sample because this error happen only in production and only for a rare amount of users. There are no relevant code changes between 4.4.5 and 4.5.0 which could fix this issue, therefore im sure this issue still exists in 4.5.0. Are those 3 stack traces not helpful?

[danagbemava-nc]

Hi @tecbot, it's standard procedure to request reporters to try on newer versions whenever a bug is reported on an "older" version of a package.

Since this is a production bug with no steps to reproduce, I'll be labeling this based on the crash logs provided above.
