401 on _apis/Contribution/dataProviders/query?

[clement-nardi]

Hi!

Thank you for this great tool!

In the logs I systematically get an error at startup:

{"level":"error","caller":"azure-devops-exporter/metrics_resourceusage.go:59","msg":"response status code is 401 (expected 200), url: https://dev.azure.com/***/_apis/Contribution/dataProviders/query?api-version=5.1-preview.1","collector":"ResourceUsage","stacktrace":"
main.(*MetricsCollectorResourceUsage).collectResourceUsageAgent
/go/src/github.com/webdevops/azure-devops-exporter/metrics_resourceusage.go:59
main.(*MetricsCollectorResourceUsage).Collect

"}

Do you know which permission is needed to access this API?
I found this documentation, but it didn't help much..

I'm actually not sure what impact this error has on the tool.
