I'm also facing the exact same issue right now.

[markusaksli-nc]

Hi @bhanugummana @muhammad-curate
Could you be facing this due to https://github.com/flutter/flutter/issues/66122? That was fixed on master so could you try switching to the latest flutter master?
Thank you

[bhanugummana]

@markusaksli-nc updated to master still facing the same issue. Thank you

Same result as well. Switching to master channel has the same issue for me.

@bhanugummana Could you please provide a minimal complete reproducible code sample for your exact setup of this

doc.set or doc.get an object that has a list of DocumentReference inside it

[creativecreatorormaybenot]

@markusaksli-nc Are you sure this is an issue with DocumentReference list?

Because we see Invalid argument: Maximum call stack size exceeded in one project that does it and also see it in another project that does not use it.

[markusaksli-nc]

The sample I provided seems to show that is an issue with a DocumentReference list specifically. There were other issues with js object list conversions on web (see https://github.com/FirebaseExtended/flutterfire/issues/4063). Not sure if it is fixed yet since as far as I know that PR hasn't rolled into a plugin version bump yet.

What other case specifically are you referring to?

[creativecreatorormaybenot]

@markusaksli-nc Nevermind, were able to fix it :)

Until https://github.com/FirebaseExtended/flutterfire/pull/4212 (fix PR) is merged, you can use the following dependencies:

      ref: fix-document-reference-check
