Can't create a $0 amount stripe_plan

[ukd1]

resource "stripe_plan" "base_platform_fee_0" {
  product    = stripe_product.base_platform_fee.id
  nickname   = "$0/month (Annual Prepaid)"
  amount     = 0
  interval   = "month"
  usage_type = "licensed"
  currency   = "usd"
}

ends up posting this to stripe:

{
  "active": "true",
  "billing_scheme": "per_unit",
  "currency": "usd",
  "interval": "month",
  "interval_count": "1",
  "nickname": "$0/month (Annual Prepaid)",
  "product": "prod_FM8XCymxvqHCB5",
  "usage_type": "licensed"
}

raising a 400 from stripe:

{
  "error": {
    "message": "If the billing scheme is set to per_unit, the amount parameter must be set.",
    "param": "amount",
    "type": "invalid_request_error"
  }
}

TF errors:

Error: {"status":400,"message":"If the billing scheme is set to per_unit, the amount parameter must be set.","param":"amount","request_id":"req_REKuHBMBjmHbEo","type":"invalid_request_error"}

Digging a little, it appears to be as on https://github.com/franckverrot/terraform-provider-stripe/blob/master/stripe/resource_stripe_plan.go#L188 getOk is used and returns false if something is zero - https://github.com/franckverrot/terraform-provider-stripe/blob/9996396e8f9aa66be41ec2d79cc01d094b5f3bf6/vendor/github.com/hashicorp/terraform/helper/schema/resource_data.go#L88 specifically on https://github.com/franckverrot/terraform-provider-stripe/blob/9996396e8f9aa66be41ec2d79cc01d094b5f3bf6/vendor/github.com/hashicorp/terraform/helper/schema/resource_data.go#L102

Seems like ValueOrZero might be useful; but not sure what the side effects are when it's supposed to be nil...

Hey there, thanks for reporting this.

Do you wanna give a try sending a PR or would you like me to investigate (not sure I'll have time this week though so you can go ahead and try if you'd like to speed things up.) Thanks!

@franckverrot we may have time to do a PR in a couple of weeks time - this is being put as an optional part of some internal work we're doing! If we start the work, I'll make sure we check here / comment here that we are doing so!

Implemented in https://github.com/franckverrot/terraform-provider-stripe/releases/tag/v1.7.0

Thanks @trea and thanks @ukd1 for reporting!
