Hi :)
Any updates on this problem?

[marshalys]

To get 'method handler crashed' because the call not put config parameter(3rd parameter), so the config is nil.
we need to check if config is nil

[marshalys]

@yperbasis can you help to review the code?

[awskii]

Thanks @quick-pawiromitchel for reporting and kudos to @marshalys for fixing.

[marshalys]
