I know you asked not to truncate the output but I can't easly risk giving you a full output file.

Expected output

incapsula_incap_rule.delete-xaspnet-response-header: Destruction complete after 1s

Actual output

╷
│ Error: Error status code 500 from Incapsula service when deleting Incap Rule XXXXXX for Site ID XXXXXXX: Unknown error. Contact support

Steps to reproduce

1. create a imperva site in tf
2. create three or more incap rule for the above site in tf
3. apply the tf
4. confirm it's built
5. destroy the tf
6. error code should appear.

Additional factoids

Hey Team,

Creating the incap rules works 100% of the time

When I go do delete these three incap rules from the site via a destroy run, the destruction of the resource fails with the generic 500 error code.

From my testing I suspect it's a case of rate limiting from the imperva api as it will typically not delete two or one of the incap rules out of the three.

My actual use case leverages a csv file that holds multiple websites, this means that will fail on many of the rules being deleted as the each site is a three x multiplier.

I have a case open with Support 01627145 but I'm logging the case here to get some traction.

I'm happy to share the debug out file with someone via the imperva support team in a offline manner.

Thanks!
