I’m trying to build a resource provider and I’m getting an
impossible type assertion
. Any ideas?

This probably means your Go dependencies are not resolving correctly to a single shared solve across the full set of dependencies. Are you following the steps at e.g. https://github.com/pulumi/pulumi-tf-provider-boilerplate?

Got it - we should see about updating those links to all point at the same documentation on this. /cc @stocky-spoon-28903

@white-balloon-205 I’m trying to port a 3rd party terraform provider and it seems that the terraform provider it references isnt the same
I’m new to golang so any help would be appreciated 👍

@stocky-spoon-28903 will definitely be the expert here - I think he may have looked at the Atlas provider at some point as well...

@red-lamp-97876 did you use govendor-override for this?

@stocky-spoon-28903 no. Should I be?

Likely, yes - it’s important that we pull in the exact dependencies of an upstream terraform provider, which dep won’t do by default

@stocky-spoon-28903 not sure what’s up but the dependencies aren’t being resolved correctly with the constraints. I’m getting stuff like this:

@red-lamp-97876 I’ll take a look
(Sorry for the delay here, I’m in Europe so it was ~3 am 🙂 )
The problem I’m seeing suggests the provider isn’t vendored in the way we expect:

@stocky-spoon-28903 so I'm guessing I'll have to fork the provider's repo and change the vendor packages? This is getting way more difficult than I anticipated 🤣

I’ll take a better look at it but it sounds to me like upstream is hosed there
