GetReleaseDefinition fails when using scheduled days

When using this config in Azure DevOps:

We get this error:
"json: cannot unmarshal number into Go struct field ReleaseSchedule.environments.schedules.daysToRelease of type release.ScheduleDays"

Returned from:
releaseDefinitionObject, err := releaseClient.GetReleaseDefinition(ctx,
getReleaseDefinitionArgs)
if err != nil {
log.Fatal(err)
}

Its this function that is throwing the error:

azure-devops-go-api/azuredevops/client.go

Line 295 in 09c8cad

    
           func (client *Client) UnmarshalBody(response *http.Response, v interface{}) (err error) {

And it is used by the function:

azure-devops-go-api/azuredevops/release/client.go

Line 682 in 09c8cad

    
           func (client *ClientImpl) GetReleaseDefinition(ctx context.Context, args GetReleaseDefinitionArgs) (*ReleaseDefinition, error) {

I confirm this one
The library uses string names like "none", "Monday", "tuesday", "all", but in actual response from API we get both numbers and string numbers like 42 or "127"
