Why do I get an error when using go1.21?

[SimFG]

The following is my workflow file:

jobs: golangci: name: lint runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-go@v5 with: go-version: 1.18 - name: golangci-lint core uses: golangci/golangci-lint-action@v6 with: version: latest working-directory: ./core args: --timeout=5m --out-format=colored-line-number ./... skip-cache: true - name: golangci-lint server uses: golangci/golangci-lint-action@v6 with: version: latest working-directory: ./server args: --timeout=5m --out-format=colored-line-number ./... skip-cache: true 

I don't have a go.mod file in my root directory, but there are in the core and server directories. If I use go1.18, github action will work fine, but if I use go1.21, I will get an error that the go file cannot be found.

I guess it's because you have a problem with your go.mod
