OnCall outgoing webhook requires user field to be populated

[N3X14]

Terraform Version

• Terraform: v1.5.6
• Terraform Grafana Provider: 2.3
• Grafana OnCall: 1.3.30

Affected Resource(s)

Please list the resources as a list, for example:

• grafana_oncall_outgoing_webhook

Terraform Configuration Files

resource "grafana_oncall_outgoing_webhook" "integrationxyz_oncall_resolve" {
    provider = grafana.oncall
    name     = "Integration XYZ RESOLVE"

    user     = ""
    password = ""
    data     = "."
    team_id  = data.grafana_oncall_team.team1.id
    url      = var.webhook_url_team1
    
    forward_whole_payload = true    
}

Debug Output

Error: POST https://domain/api/v1/actions/: 400 {user: [This field may not be null.]}

Expected Behavior

The outgoing webhook should have been created. The user field is optional as per the provider's documentation and it wouldn't make sense to require it given other forms of authentication could be used (as in our case).

Actual Behavior

Terraform wasn't able to create the resource as the field was required to be not "NULL" - Note that it works just fine if you provide a string as value there.

Steps to Reproduce

1. terraform apply

References

Didn't find anything that would mention this behavior.
