MissingMethodException

[cshan (Caleb)]

Using UiPath.Azure activity package, we are trying to access the list of Blobs in a container without using an Azure Scope.

Getting the below MissingMethodException even when there are no other dependencies. Any guidance on how to resolve this?

Tried both versions 1.2 and 1.3-preview and getting the error.
1.1.8 works but we need to use 1.2 so that we can use CopyBlob outside of Azure Scope (not available in <= 1.1.8)

Full error:

Hi @cshan

kindly refer below link

Error after upgrade library: Method not found: 'Void UiPath.Core.Activities.LogMessage.set_Level(UiPath.Core.Activities.CurentLogLevel)

@Gino Thank you for the reply. I found below statement from the docs page About Libraries It is highly recommended for libraries and processes to use the same versions of dependencies, or within a difference of minor package updates, to avoid running into breaking changes. This is a best practice of developing and reusing libraries. If you encounter System.MissingMethodException when executing a process that invokes a library, you should recompile your library using dependencies with a versi…

hope this helps

[cshan (Caleb)]

Yes, it is a Runtime Exception

Thanks Nikhil, but as you can see in my screenshot, there are no other dependencies added to the project other than the UiPath.Azure activities.

There’s definitely no libraries being used, so I don’t think that link suggesting a republish of library will help me here

Hey @cshan

If you can share the project file please ?

Thanks

Hey mate, sure, I am attaching it to this message. I needed to redact all my settings information but if you have an Azure Storage Account, you can substitute your own

Is the issue still exist with Azure activities ?
