Incorrect `typecheck` failure

[jidicula]

I'm seeing an incorrect failure of typecheck invoked by golangci-lint-action@v3.1.0 in GitHub Actions: https://github.com/jidicula/vci-check/runs/5345676647?check_suite_focus=true#step:3:24

Specifically, it's throwing the error: Error: ReadAll not declared by package io (typecheck)

This is clearly incorrect, as io.ReadAll() indeed exists: https://pkg.go.dev/io#ReadAll . Perhaps it's parsing it incorrectly as a type exported by io rather than an exported function?

Running golangci-lint 1.44.2 locally on my machine does not throw this error.

Please read the README, the v3 does not install go anymore, you need to add:

- uses: actions/setup-go@v2
        with:
          go-version: '1.17'

I see incorrect typecheck failures as well, but I do set up Go:

    steps:
      - name: Checkout repository
        uses: actions/checkout@v3.0.0
        with:
          token: ${{ secrets.PAT_TOKEN }}

      - name: Setup Go
        uses: actions/setup-go@v3.0.0
        with:
          go-version: 1.17.7

      - name: Run golangci-lint
        # yamllint disable-line rule:line-length
        uses: golangci/golangci-lint-action@b517f99ae23d86ecc4c0dec08dcf48d2336abc29  # v3.1.0
        env:
          GOPRIVATE: github.com/myorg
        with:
          version: v1.44.2

Here is my config and it fixed the problem.

name: golangci-lint
on:
  push:
    tags:
      - v*
    branches:
      - main

jobs:
  golangci:
    name: lint
    runs-on: ubuntu-latest
    steps:
      - name: Setup Go
        uses: actions/setup-go@v3.0.0
        with:
          go-version: 1.17.8
          
      - uses: actions/checkout@v2
      
      - name: Check for unused Golang imports
        uses: Jerome1337/gomod-action@v1.0.0
        
      - name: golangci-lint
        uses: golangci/golangci-lint-action@v3.1.0
        with:
          # Optional: version of golangci-lint to use in form of v1.2 or v1.2.3 or `latest` to use the latest version
          version: v1.45.2

          # Optional: working directory, useful for monorepos
          working-directory: ./be

          args: -v

I have this problem currently as well with this config:

  golangci:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/setup-go@v3
        with:
          go-version: "1.19.2"
      - uses: actions/checkout@v3
      - name: golangci-lint
        uses: golangci/golangci-lint-action@v3.2.0
        with:
          version: v1.50

My error was related to that a dependency to a private module didn't get downloaded correctly.
Really weird to get a typecheck-lint-error on this though.

For me the problem was the combination between the go version and the golangci-lint version. You can specifically set both to latest to see if that is the case.
