go.mode - make error

[slowikDevOps]

Hello, when I used make I got error:

slovik@nbkpcsi713:~/pgpool2_exporter$ make
go: errors parsing go.mod:
pgpool2_exporter/go.mod:5: unknown directive: toolchain
make: *** [Makefile:24: promu] Error 1

Before changes in go.mod:

module github.com/pgpool/pgpool2_exporter

go 1.22

toolchain go1.22.1

require (
github.com/blang/semver v3.5.1+incompatible
github.com/go-kit/log v0.2.1
github.com/golang/protobuf v1.5.3 // indirect
github.com/lib/pq v1.10.2
github.com/prometheus/client_golang v1.15.1
github.com/prometheus/common v0.44.0
github.com/prometheus/procfs v0.9.0 // indirect
golang.org/x/sys v0.9.0 // indirect
google.golang.org/protobuf v1.30.0 // indirect
)
....

After changes in go.mod (delete toolchain go1.22.1 - is okay)

module github.com/pgpool/pgpool2_exporter

go 1.22

require (
github.com/blang/semver v3.5.1+incompatible
github.com/go-kit/log v0.2.1
github.com/golang/protobuf v1.5.3 // indirect
github.com/lib/pq v1.10.2
github.com/prometheus/client_golang v1.15.1
github.com/prometheus/common v0.44.0
github.com/prometheus/procfs v0.9.0 // indirect
golang.org/x/sys v0.9.0 // indirect
google.golang.org/protobuf v1.30.0 // indirect
)

Have a nice day!
