Debug Output

2019/09/23 12:34:56 [WARN] Provider "google-beta" produced an invalid plan for module.research.module.gcp_node_pool.google_container_node_pool.node_pools[2], but we are tolerating it because it is using the legacy plugin SDK.
    The following problems may be the cause of any confusing errors from downstream operations:
      - .management[0].auto_repair: planned value cty.False does not match config value cty.NullVal(cty.Bool)
      - .node_config[0].preemptible: planned value cty.False does not match config value cty.NullVal(cty.Bool)
      - .node_config[0].taint[1].effect: planned value cty.NullVal(cty.String) does not match config value cty.StringVal("NO_SCHEDULE")
      - .node_config[0].taint[1].key: planned value cty.NullVal(cty.String) does not match config value cty.StringVal("nvidia.com/gpu")
      - .node_config[0].taint[1].value: planned value cty.NullVal(cty.String) does not match config value cty.StringVal("present")

Panic Output

Expected Behavior

+ taint {
     + effect = "NO_SCHEDULE"
     + key    = "nvidia.com/gpu"
     + value  = "present"
}

Actual Behavior

+ taint {}

Steps to Reproduce

Apply the configuration defined above with:

1. terraform apply

Important Factoids

it works for anything else in "key" field. Even "nvidia.com/gpu " "works", of course it is not valid later during api validation but at least this outpus looks right:

+ taint {
     + effect = "NO_SCHEDULE"
     + key    = "nvidia.com/gpu "
     + value  = "present"
}
