You may see this error if you will need to link your assigned payment method to a bank type account in Xero.
Here are two cases in which you can receive this error message:
- The bank account is no longer active in Xero, or was archived in Xero:
In order to fix this, refresh your Chart of Accounts, and select the relevant bank account.
- The payment method is linked to an account that is not a 'bank type account' in Xero:
To fix, choose a different Payment Method which is linked to a bank type account, or link your current Payment Method to a Bank Account.
