Diagnostics Settings to direct Audit Logs to Event Hub for APIM instance using Bicep

Question

Hi

I would like to configure the diagnostic settings for a newly deployed APIM instance using Bicep.

Have referred to the guidance here--> https://learn.microsoft.com/en-us/azure/azure-resource-manager/bicep/scenarios-monitoring

When I'm deploying the following code as part of the APIM module

resource apimdiaglogs 'Microsoft.Insights/diagnosticSettings@2021-05-01-preview' = {

  name: apim.name

  scope: apim

  properties: {

    eventHubName: 'evname'

    eventHubAuthorizationRuleId: eventhubauthruleid

    logs: [

      {

        enabled: true

        category: 'AuditLogs'

      }

    ]

  }

}

I've also used categoryGroup and no matter what the value I set that for, the error remains the same.

However, I'm getting the following error:

Category 'audit' is not supported. (Code: BadRequest, Target:)

I'm allowed to do this through Azure Portal.

Can someone provide inputs on where I'm possibly going wrong?

Thanks
