Terraform plan fails with "Disabled API Key" when using provider version 3.18.1+

Confirmation

[X] My issue isn't already found on the issue tracker.
[X] I have replicated my issue using the latest version of the provider and it is still present.

Terraform and Imperva provider version

Terraform v1.4.6
on linux_amd64

    provider registry.terraform.io/imperva/incapsula v3.20.0

Affected resource(s)

We are using the incapsula_site resource but the error is from the provider (see below)

Terraform configuration files

provider "incapsula" {
  api_id  = data.google_secret_manager_secret_version.incapsula_api_id.secret_data
  api_key = data.google_secret_manager_secret_version.incapsula_api_key.secret_data
}

Debug output

I trimmed the rest of the debug output out cause it was a mile long. If you would like to see it all, let me know.

Panic output

No response

Expected output

No error from the provider and the imperva_site resource is shown in the plan output as expected.

Actual output

448│ Error: Error from Incapsula service when checking account: {"res":9418,"res_message":"Disabled API Key","debug_info":{"id-info":"999999"}}

Steps to reproduce

Make sure you are not pinning to a specific Incapsula provider version (aka use latest or version 3.18.1+)
Configure the provider with a known working API ID and KEY
Configure an imperva_site resource block
Run terraform plan

Additional factoids

This issue seems to only affects provider version 3.18.1 and above, including latest, which at the time of writing this is 3.20.0. Using a known working API key or generating a new one does not make a difference. I have validated that the API key works via local Postman tests. Provider version 3.18.0 and below are not affected by this issue. We are pinning to 3.18.0 for now until this is fixed.
