In Bitbucket Cloud, when trying to add payment details from Bitbucket Settings > Plan details the State field will in some cases return the error 'Invalid state' even if the name added is a valid state (see screenshot). This will prevent the user from completing the process and make the payment.

The issue is that state abbreviations are expected, but the error message does not make this clear.

Please note that you should be able to update your billing details if you enter the state abbreviation, instead of the full name of the state.

For example, for Indian state Haryana, instead of entering Haryana, you will need to enter the state abbreviation HR instead.
