Debug Output/Panic Output

Error: parsing "2eadfd87-945c-4e78-bbbd-fed4496fb0d9": parsing the ServicePrincipal ID: the number of segments didn't match
│ 
│ Expected a ServicePrincipal ID that matched (containing 2 segments):
│ 
│ > /servicePrincipals/servicePrincipalId
│ 
│ However this value was provided (which was parsed into 0 segments):
│ 
│ > 2eadfd87-945c-4e78-bbbd-fed4496fb0d9
│ 
│ The following Segments are expected:
│ 
│ * Segment 0 - this should be the literal value "servicePrincipals"
│ * Segment 1 - this should be the user specified value for this servicePrincipalId [for example "servicePrincipalId"]
│ 
│ The following Segments were parsed:
│ 
│ * Segment 0 - not found
│ * Segment 1 - not found
│ 
│ 
│   with azuread_service_principal_password.ent_main_secret,
│   on temp.tf line 47, in resource "azuread_service_principal_password" "ent_main_secret":
│   47:   service_principal_id = azuread_service_principal.ent_main.object_id

Expected Behaviour

Either the ServicePrincipalId was produced with the number of segments expected by azuread_service_principal_password or the azuread_service_principal_password expects or handles just the objectid of the service principal

Actual Behaviour

Error, number of segments not matching

Steps to Reproduce

terraform apply

Important Factoids

Thank you for taking the time to open this issue. I am going to move it over to the Terraform AzureAD Repo since that is where these resources are found.

The new doc shows that it now expects the actual service principal ID but this breaking change is not documented anywhere in the upgrade guide.

resource "azuread_application" "example" {
  display_name = "example"
}

resource "azuread_service_principal" "example" {
  client_id = azuread_application.example.client_id
}

resource "azuread_service_principal_password" "example" {
  service_principal_id = azuread_service_principal.example.id
}

Thanks @mablouin - this has fixed the issue for me!
