This looks good but I got an error when testing this integration.

What is the error

I ran mantis with your Namecheap extension but I got the following error.

Possible causes

This doesn't seem to be an issue with your code. I have two domains in my Namecheap account and this error happens when the the records are enumerated for a domain that uses external Nameserver.

Possible resolution

1. Namecheap doesn't allow granular control over API key permissions. Can you add a check in your integration so that only the enumeration happens for the onboarded TLDs only and not all the domains on the nameserver. You can refer to this PR where the person added checks for TLDs in-scope. You can use the same CLI argument and add logic to your integration.
2. Can you add exception handling for such cases? (Optional)

[madhav6ram]

@0xbharath I will test both these suggestions and update my PR.

[0xbharath]

You can refer to this PR #53

[madhav6ram]

@0xbharath This issue must be fixed when running mantis scan with -is or --in_scope flag. I completed adding this flag functionality into into the arg parser (arg_parse.py).

Note: I only catch this error '2030288 - domain is not using proper DNS servers'. If I need to handle any others let me know.

[0xbharath]

This should be good. I'll review this and let you know.

[0xbharath]

This has been delayed on my end. Will review this today.

[0xbharath]

This is good from a functionality PoV.

@Prateek-Thakare Can you go through the code and merge this?

[Prateek-Thakare]

Reviewed the code, Bharath has tested the code. Made changes to the files not needed.
