Relevant Error/Panic Output Snippet

Plan

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  - destroy

Terraform will perform the following actions:

  # vault_generic_endpoint.disable_upsert["transit"] will be destroyed
  # (because vault_generic_endpoint.disable_upsert is not in configuration)
  - resource "vault_generic_endpoint" "disable_upsert" {
      - data_json            = (sensitive value) -> null
      - disable_delete       = false -> null
      - disable_read         = false -> null
      - id                   = "transit-example/config/keys" -> null
      - ignore_absent_fields = false -> null
      - path                 = "transit-example/config/keys" -> null
      - write_data           = {} -> null
      - write_data_json      = jsonencode({})
    }

Plan: 0 to add, 0 to change, 1 to destroy.

On apply

vault_generic_endpoint.disable_upsert["transit"]: Destroying... [id=transit/config/keys]

### Terraform Configuration Files

```hcl

  path                      = "transit-example"
  type                      = "transit"
}

resource "vault_generic_endpoint" "this" {
  path      = "transit-example/config/keys"
  data_json = <<EOT
{
  "disable_upsert": false
}
EOT

  depends_on = [vault_mount.this]
}

Looks like I may be hitting this as well. Using the example code https://registry.terraform.io/providers/hashicorp/vault/latest/docs/resources/generic_endpoint#example-usage "u1_entity" I'm also getting the Code 405 error.

I noticed that the error shows URL: GET https://vault.local:8200/v1/identity/lookup/entity however when I successfully run this command via CLI it's uses PUT via vault write command instead.

I suspect that this resource is not sending the correct command and ignoring the configuration of disable_read

terraform v1.6.4 vault provider v3.23.0

Update: I revisited this config with fresh eyes. it appears that because I used vault_generic_endpoint without disable_read = true once it was preventing any further plan from succeeding. Once I did a terraform state rm to that resource and applied again with disable_read = true it worked as expected. So watch out for that trap with vault_generic_endpoint.

I'll re-test. I think I did cover this case too and the behavior was the same.

Happening to me as well. Hit this issue after being redirect from https://github.com/hashicorp/terraform-provider-vault/issues/1715.
