Error with ValidationScheme has no field or method IsValidMetricName

[heliapb]

From a dependabot pr https://github.com/paulojmdias/lokxy/pull/84/files git and error with client_golang v1.23.2

# github.com/prometheus/client_golang/prometheus/internal
Error: ../../../go/pkg/mod/github.com/prometheus/client_golang@v1.23.2/prometheus/internal/go_runtime_metrics.go:70:34: model.LegacyValidation.IsValidMetricName undefined (type model.ValidationScheme has no field or method IsValidMetricName)

Seems this change was introduced in https://github.com/prometheus/client_golang/pull/1859/files. Could you pls check. Thanks

Had the same issue, found the solution: https://github.com/prometheus/common/releases/tag/v0.66.0

It's a breaking change in prometheus/common. Use e.g.

expfmt.NewTextParser(model.LegacyValidation)

instead of

expfmt.TextParser{}
