'Upgrading Microsoft.Bot.Builder.LanguageGeneration to 4.15.0 results in fromFile() error
Upgrading Microsoft.Bot.Builder.LanguageGeneration from 4.14.1 to 4.15.0 results in new errors about the fromFile() method. Couldn't find any solution or similar issues on the internet yet. This holds us from upgrading so any feedback is welcome.
/UnitTests/bin/Debug/net5.0/Resources/Lg/General.lg line 25:2 - line 25:39: Error occurred when parsing expression 'fromFile('../Cards/HelpCard.json')'. fromFile does not have an evaluator, it's not a built-in function or a custom function.

For someone who needs sample on how to add it.
Add it like this in startup.cs-> ConfigureServices method.
Also on lg file - you dont have to create manually lg file - it will be generated in backend.
You just have to add your content in bot responses which is the content it will be generated in lg file in backend - you can open the same solution in visual studio and see it.
