Error: rpc error: code = Unavailable desc = transport is closing

Steps to Reproduce

1. terraform apply -auto-approve

[yannickstruyf3]

Hi @sachin433,

This error is caused by this block:

project_reference = {
   "kind" = "project"
   "name" = "Performance"
}

Would it be possible to pass the project uuid instead of the name? For example:

  project_reference = {
    kind = "project"
    uuid = "my-id-string"
  }

We will also check from our side how we can optimise the error handling.

@marinsalinas @coderGo93

[kruftik]

project_reference = {
   "kind" = "project"
   "name" = "Performance"
}

why the resource schema is so redundant? if the section is called project_reference, what is the point to embed kind field inside? why not to use any kind of a abstract section name (e.g. 'reference') or omit kind field entirely?

[yannickstruyf3]

@kruftik, we are following the Nutanix API schema's as close as possible. However, we are constantly looking at improvements and we will also consider omitting the kind field (easy workaround would be to put "project" as default value).
@marinsalinas

[sachin433]

@yannickstruyf3 thanks for spotting the error. I kind of missed it.
