golint returns the following errors but golangci-lint does not. Any idea what went wrong?

Hello,

golangci-lint applies some exclusions by default:

Independently from option exclude we use default exclude patterns,
it can be disabled by this option. To list all
excluded by default patterns execute golangci-lint run --help.
Default value for this option is true.
exclude-use-default: false
