System.MissingMethodException: Method not found: 'Void Pulumi.ProviderResource..ctor'...

Muchaszewski commented 3 months ago

What happened?

Instantiate new provider from code

    var cloudflareProvider = new Cloudflare.Provider("cloudflare-provider", new ProviderArgs 
    {
        ApiToken = ApiToken
    });

or

        Provider = new MongodbAtlasProvider("mongodbatlas", new ProviderArgs
        {
            PublicKey = PublicApiKey,
            PrivateKey = PrivateApiKey
        });

This code worked ~3 months ago, and I did change nothing in my code base. Now I could finally get back to this deployment and I encountered the following issue on ALL providers.

 error: Running program 'project\bin\Debug\net6.0\vinode-deployment.dll' failed with an unhandled exception:
    System.MissingMethodException: Method not found: 'Void Pulumi.ProviderResource..ctor(System.String, System.String, Pulumi.ResourceArgs, Pulumi.CustomResourceOptions)'.
       at new Pulumi.Cloudflare.Provider(string name, ProviderArgs args, CustomResourceOptions options)
       at new Project.Providers.CloudflareConfig(Config config) in project/Providers/Cloudflare.cs:line 18

Right now, after running this code for all providers, I get this error.

I tried:

Cleaning the solution/Debug folder
Clean building
Updating to latest pulumi version (from 3.118.0 to 3.128.0)
Updating .NET from 6.0 to 8.0
Updating all nuget packages (did not noted the version of the change)
Restarting PC

The only thing that helps is copy-pasting the decompiled code, and implementing it manually and using that instead. But this workaround is messy and I wish I would not have to do that.

Example

    var cloudflareProvider = new Cloudflare.Provider("cloudflare-provider", new ProviderArgs 
    {
        // You might need to configure the Cloudflare provider by setting your Cloudflare API token.
        ApiToken = "<YOUR_CLOUDFLARE_API_TOKEN>" // Replace this with your actual API token.
    });

or

        Provider = new MongodbAtlasProvider("mongodbatlas", new ProviderArgs
        {
            PublicKey = PublicApiKey,
            PrivateKey = PrivateApiKey
        });

Exception

 error: Running program 'project\bin\Debug\net6.0\vinode-deployment.dll' failed with an unhandled exception:
    System.MissingMethodException: Method not found: 'Void Pulumi.ProviderResource..ctor(System.String, System.String, Pulumi.ResourceArgs, Pulumi.CustomResourceOptions)'.

Note, that after replacing all providers like that there are further errors as if the DLLs with plugins/modules were not loaded at all.

Video with debugger attached on how the issue looks, step into and step over generate the same result:

https://github.com/user-attachments/assets/36cd252f-7796-4c97-921d-68810bf71ca0

Compilation result folder has all the DLLs, and they all contain all correct definitions (after decompilation)

Hi there @Muchaszewski thanks a lot for filing the issue! :pray: any chance you could try the reverting Pulumi from v3.66.0 to v3.65.0 or removing the Pulumi nuget package entirely? (since it is a dependency of the providers)

We did add a new optional parameter for the constructor of Provider:

public ProviderResource(
            string package,
            string name,
            ResourceArgs args,
            CustomResourceOptions? options = null)

became:

public ProviderResource(
    string package,
    string name,
    ResourceArgs args,
    CustomResourceOptions? options = null,
    RegisterPackageRequest? registerPackageRequest = null)

Which I assumed to be non a breaking change (the new parameter is optional) but it looks like existing .NET SDKs built with older versions of Pulumi looks for that exact parameter, regardless of optionalness (not binary compatible)

I can repro using the provider from Pulumi.Random v4.16.3 (built with Pulumi v.3.64.0) and it gives the same error

Zaid-Ajaj commented 3 months ago

Hi @Muchaszewski version 3.66.1 has been published and I've tested that the issue no longer appears with providers, invokes or resources. Please give it a try and let us know if you encounter any issues.

The error is gone! Thank you for your fast response and for fixing the issue!
