Migration problems cannot generate protos any longer

[go-aegian]

I followed all steps to migrate and I'm also using knit

npx @connectrpc/connect-migrate@latest

Scanning... ✓
    1 package.json file

    1 buf.gen.yaml file
It looks like you are already up to date 

But I'm getting these errors when generating protos

npx buf generate

Failure: decode buf.gen.yaml: invalid as version v2: could not unmarshal as YAML: yaml: unmarshal errors:

Anybody can provide me with help?

Looks like you are using a v2 buf.gen.yaml file with v1 naming conventions. The property name is no longer valid with v2.

If you are using local plugins, change name to local and it should fix the issue. More details here.

Also just out of curiosity, was this working prior to running the migration tool? The migration tool makes changes to your plugins, but it should not change your version from v1 to v2.

[go-aegian]

my bad the property name I did not change it, yes migration tool did not change v1 to v2 that was me doing it manually.

now after updating buf to version 1.47.2 and trying to generate again I get this errors, don't know where to get connect-go and knit-ts since it was long ago I had all this running prior to upgrading, could you please help me on this?

With buf.gen.yaml v2, you need to specify local: protoc-gen-es.

I suggest to revert, and run buf config migrate. It'll automatically migrate buf.gen.yaml to v2 and make the necessary changes.

Or keep buf.gen.yaml at v1 - you don't need to upgrade the config file, and can do that separately.

If you want to use local for the plugins, you'll have to install those locally using the ecosystem for each (if not installed already). So for example:

• To install protoc-gen-connet-go, you use go install as specified here
• To install protoc-gen-knit-ts, you use npm install as specified here

As an alternative though, you can just use the remote plugins found on the BSR and you don't have to install anything locally. To do so, change local to remote and change the values to the path on the BSR. You can find the configuration options for Connect-Go here and for Knit here.

Thank you so much for your help. All has been generated successfully.

Just reopened as I was trying to use the plugins locally and when installing following the documentation on the links you provided me with I get these errors. Any light on them of what I'm doing wrong?

Hey! Are you trying to use both knit and connect?
