[Android] Firestore: Couldn't put object of type Plugin.Firebase.Android.Firestore.DocumentReferenceWrapper into HashMap about plugin.firebase

[TobiasBuchholz]

Hmm, after running your test project both button clicks seemed to work, see the screenshots:

I've created a test for it myself and also couldn't reproduce this errror. If I'm looking at your stacktrace, I think the commit 984f79c has fixed this issue already and was released with the plugin version 1.1.0.

Maybe you have some older version cached or something like this? Otherwise I've no idea how this could be possible.

Hi @TobiasBuchholz , please find this MRE to reproduce the issue on Android : PluginFirebase_Issue_55.zip
All you need to do is pressing the button specific for this issue

Thanks in advance !

Hello @TobiasBuchholz , did you test the sample app with a reference to your last released NuGet ?
Because I tried it with a direct reference to your project (not the NuGet) for debug purpose, and it's exactly as you said : the error is not reproducible...

Would it be possible that the NuGet has been released without the fix ? (e.g. Merge conflict, ...)

[TobiasBuchholz]

I've just unpacked your zip file, opened the project, restored the nuget packages and started it. The project is referencing the plugin version 1.1.2 and if you decompile the package you can see the code for the fix is contained:

So I still believe there is no problem and you can close the issue if you agree.

You were right @TobiasBuchholz , I completely forgot that I had referenced a local version I made of your package, with the exact version number ... obviously this has led to mismatch the actual one I did want to target !

Indeed, here is what mentions the documentation about package references :
For projects using the PackageReference format, NuGet uses local sources first, then sources on network shares, then HTTP sources, regardless of the order in the configuration files..

Hence, the solution I opted for is creating a nuget.config with a packageSourceMapping section for mapping the right package sources, whether it's nuget.org or local path.

And I was able to confirm it now downloads from the official package source :

Package source mapping matches found for package ID 'Plugin.Firebase' are: 'nuget.org'.
  GET https://api.nuget.org/v3-flatcontainer/plugin.firebase/index.json
  OK https://api.nuget.org/v3-flatcontainer/plugin.firebase/index.json 229ms
  GET https://api.nuget.org/v3-flatcontainer/plugin.firebase/1.1.2/plugin.firebase.1.1.2.nupkg
  OK https://api.nuget.org/v3-flatcontainer/plugin.firebase/1.1.2/plugin.firebase.1.1.2.nupkg 219ms

Referencing your package from the right source did fix the issue, closing ticket, thanks Tobias for your help.
