The requested action could not be performed, semantically incorrect, or failed business validation. INSTRUMENT_DECLINED: The instrument presented was either declined by the processor or bank, or it can't be used for this payment. This means that the user needs to use a different payment method. This is not an issue with Upgrade.Chat but has to do with the customer's payment method.
This means that the bot:
Wasn't placed above the role for sale in the Discord role list
Didn't have permissions to invite the user or give them a role
Didnt have permission to view the channel or send messages
This means that the bot was trying to add a role that was paid for but the member was not in the server. This can be for many reasons such as:
YOU DIDN'T GIVE THE BOT INVITE PERMISSIONS TO ALL CHANNELS OR CHANNELS IN YOUR SERVER IT NEEDS.
The user didn't accept the invite to join your server after paying.
The user is banned from your server for whatever reason.
The user paid but didn't validate their account email yet.
