I have created a custome activity to add document in firestore database.
This works in trial version of uipath. But throws below error in licensed version.
I have manually downlaoded the Google.Api.Gax.Grpc package and updated but no luck.
I have add the registry ```
reg add “HKLM\Software\Microsoft\Fusion” /v EnableLog /t REG_DWORD /d 1 /f
reg add “HKLM\Software\Microsoft\Fusion” /v ForceLog /t REG_DWORD /d 1 /f
reg add “HKLM\Software\Microsoft\Fusion” /v LogFailures /t REG_DWORD /d 1 /f
reg add “HKLM\Software\Microsoft\Fusion” /v LogResourceBinds /t REG_DWORD /d 1 /f
reg add “HKLM\Software\Microsoft\Fusion” /v LogPath /t REG_SZ /d C:\FusionLog\

if not exist "C:\FusionLog" mkdir C:\FusionLog

but no luck.

Th error is 

**Cannot load assembly: C:\Users\nagbn\.nuget\packages\google.api.gax.grpc/3.0.0\lib/net461/Google.Api.Gax.Grpc.dll : System.TypeLoadException: Method 'DisposeAsync' in type 'Google.Api.Gax.Grpc.AsyncResponseStream`1' from assembly 'Google.Api.Gax.Grpc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=3ec5ea7f18953e47' does not have an implementation.**

1, Import assembly in your xaml from import functionalty.
2. Open your XAML file in notepad and check assembly reference is added, if not manually add assembly.
3. Check your project.json, does it reference to your assembly.

No luck. Attaching the files. Please suggest.Project_Json.txt (998 Bytes) main_XAML.txt (3.2 KB) studiologs.txt (143.5 KB)
