@wope4455 Did you specify a timeout block when defining the resource?

The default timeout for subscriptions is 10 minutes, but you can adjust them via the timeout block (see https://registry.terraform.io/providers/SAP/btp/latest/docs/resources/subaccount_subscription#timeouts)

@lechnerc77 : thanks for the hint - I haven't used this timeout block - but I would expect that the script would generate a message when reaching that point and does not crash.

@wope4455 The handling of the retry block is part of the Terraform Framework, so we have only limited influence on the abort that happens in your case. But we will evaluate if we can influence the behavior on a lower execution level (namely in our client) to exit more gracefully
