'Metadata generation failed' when updating Microsoft.NET.Sdk.Functions to 4.1.3

[JasonAndersen7]

I am trying to update an Azure Function project from .NET Core 3.1 to .NET 6. When updating the Microsoft.NET.Sdk.Functions from 3.0.11 to 4.1.3 or later, I can no longer build the project. Instead, I get the following errors in the Error List:

• System.ArgumentException: Object of type 'Mono.Cecil.TypeReference' cannot be converted to type 'System.Type''.
• Metadata generation failed.

Similar to #585
This problem seems to be introduced by #547.

Error System.ArgumentException: Object of type 'Mono.Cecil.TypeReference' cannot be converted to type 'System.Type'.

4.1.3 or later, I can no longer build the project.

Just to confirm, If you downgrade to 4.1.2 version of Microsoft.NET.Sdk.Functions, build works?

[JasonAndersen7]

Hello kshyju,
Thank you for responding, we were able to use version 4.0.0 and version 4.0.1 but for all other versions later than 4.0.1 the build does not work

@JasonAndersen7 I could not repro this issue. Would you be able to share a minimal repro? A GitHub repo will be great.

HI Kshyju,
I was mainly curious to see if this is a known issue or not.
Unfortunately our code is proprietary and cannot be shared
Thank you for your assistance

@kshyju Can you check the above comments.

I encountered a similar issue that brought me here.
I've created a small GitHub repo to reproduce the error:
