plugin prost-crate: The system couldn't find the given file. (os error 2)

[teamplayer3]

My directory structure:

- root
  - api-crate
    - src
    | Cargo.toml
  - proto
    | buf.yaml
  | buf.gen.yaml
  | buf.work.yaml 

protoc-gen-prost-crate version v0.3.1

Now I run buf generate in the root directory, and it exits with error:

plugin prost-crate: The system couldn't find the given file. (os error 2)

buf.gen.yaml:

version: v1
plugins:
  - remote: buf.build/prost/plugins/prost:v0.2.1-1
    out: api-crate/src/gen
    opt:

We ran into this issue as well after upgrading to v0.2.2; for now we're getting around it by reverting to v0.2.1, as it seems like something broke in the latest release.

@drivasperez Which crate did you revert to v0.2.1? My protoc-gen-prost-crate crate is at v0.3.1

Apologies for the ambiguity:

protoc-gen-prost: 0.2.1

protoc-gen-prost-crate: 0.3.1

@drivasperez Ok, but as I can see the newest version of protoc-gen-prost-crate is 0.3.1 or am I wrong. I get this error with 0.3.1.

I found my problem. I have to specify the path to the Cargo.toml in opt like gen_crate=./api-crate/Cargo.toml. As default, it uses only Cargo.toml as a path. Somehow, this is not based on the out option.
