Get Wafv2 Web ACL freezes the terminal

[castodius]

Describe the bug

Attempting to get a Wafv2 Web ACL makes the terminal freeze.

Expected Behavior

Interactive mode displaying required parameters immediately when selecting the operation.

Current Behavior

The terminal freezes when selecting the operation.

Reproduction Steps

• Make sure the CLI is configured for interactive mode, I am setting the variable _AWS_CLI_AUTOPROMPT to on-partial in my terminal
• Start an interactive session by for example running "aws wafv2"
• Start typing "get-web-acl" and select it
• The terminal should freeze at this point

Possible Solution

No response

Additional Information/Context

Other get operations such as "aws lambda get-function" displays available parameters just fine. I assume something must be off with the config for get webacl.

CLI version used

2.11.21

Environment details (OS name and version, etc.)

macOS Big Sur, Version 11.7.6

Thanks @castodius for reporting this issue. I could reproduce this as well. It's strange that it's just occurring for aws wafv2 get-web-acl.

At this auto-prompt screen I tried to go down and select an option and that works after ~10 seconds (but the options never get highlighted when I press the up and down arrows):

Some further review is needed here into what could be causing this and which other commands may be affected.
