The request body must contain the following parameter: 'grant_type'

unexpected response code '400': {"error":"invalid_request","error_description":"AADSTS900144: The request body must contain the following parameter: 'grant_type'.

I am trying to create Bearer token for a Azure service principal.

Provider.tf contains

provider "restapi" {
  alias = "restapi_bearer"
  uri   = "https://login.microsoftonline.com/"
  headers = {
    Content-Type = "application/json"
  }
  create_method        = "POST"
  write_returns_object = true

}

resource.tf contains

resource "restapi_object" "sp" {
  path = "/${azuread_service_principal.tenant_sp.application_tenant_id}/oauth2/v2.0/token"
  data = jsonencode({
    grant_type    = "client_credentials"
    client_id     = "${azuread_service_principal.tenant_sp.application_id}"
    scope         = "2ff814a6-3304-4ab8-85cb-cd0e6f879c1d%2F.default"
    client_secret = "${azuread_application_password.tenant_sp.value}"
  })
}

My data has grant_type set and still i am getting 400

Am i missing something or doing this wrong!

the BODY part looks empty ?

I am fighting with the very same problem. Did you find a solution for this?

resource "restapi_object" "get_token" {
path = "/api/oauth2/token"
debug = true
data = jsonencode({
grant_type = "password"
username = var.user
password = var.pwd
refresh_token = ""
code = ""
use_short_term_refresh = ""
vbr_token = ""
})
}
