Can't create Cloud Functions Actions that are larger than 4mb

[forgems]

When trying to create a nodejs action from zipfile terraform apply fails with following error

Error: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (8316886 vs. 4194304)

After briefly searching on the internet this could be an issue with the terraform not accepting variables larger then 4mb in it's state.

Terraform Version

Terraform v0.12.24
+ provider.ibm v1.10.0

Affected Resource(s)

Please list the resources as a list, for example:

• ibm_function_action

Terraform Configuration Files

terraform {
    required_providers {
        ibm = "~> 1.10"
    }
}

provider ibm {
  ibmcloud_api_key      = var.ibmcloud_api_key
  region                = var.region
}

data "ibm_resource_group" "resource_group" {
  is_default = true
}

resource "ibm_function_namespace" "namespace" {
    name = var.namespace
    resource_group_id = data.ibm_resource_group.resource_group.id
}

resource "ibm_function_action" "test_action" {
  name = "test_action"
  namespace = ibm_function_namespace.namespace.name
  exec {
    kind = "nodejs:10"
    code = filebase64("../test_action.zip")
  }
  publish = true
  user_defined_annotations = jsonencode([
    {
        "key": "web-export",
        "value": true,
    },
    {
        "key": "hash",

Steps to Reproduce

1. terraform apply

[anilkumarnagaraj]

This is a known limitation with terraform. There is already an issue opened in terraform for the same.
hashicorp/terraform-provider-local#28
We will look for a possible workaround and get back to you.

[anilkumarnagaraj]

Fix is available in the latest release https://github.com/IBM-Cloud/terraform-provider-ibm/releases/tag/v1.21.1

We have added a new argument 'code_path' in ibm_function_action, which will take the file path as an input.
Please refer to below link for more info:
https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/resources/function_action

ex:
resource "ibm_function_action" "my_action" {
name = "my-action"
namespace = var.cloud_functions_namespace

exec {
	kind = var.python_kind
	code_path = "bundle.zip"
}

}

The fix works great, but when executing terraform destroy I get the same error message as before:

The plugin returned an unexpected error from plugin.(*GRPCProvider).PlanResourceChange: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (6361432 vs. 4194304)

This is still an issue. It worked at some point but is broken at least with the latest version of the provider.
I cannot do anything at the moment, not even terraform refresh because of this bug.

I am using

exec {
    kind = var.node_kind
    code_path = "path/to/bundle.zip"
  }

and the error I get

The plugin returned an unexpected error from plugin.(*GRPCProvider).PlanResourceChange: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (7828501 vs. 4194304)
