Argument 1 passed to WHMCS\TransientData::retrieveByData

[HOSTEAZA]

Hello,

 

I encounter an issue with WHMCS BitPay payment gateway, that is not set invoices as paid in WHMCS.

After payment, on invoice page i have next messages:

A payment is being processed for this invoice - this is after payment is sent.
Payment is being approved - this is after all confirmations is made and status on bitpay account is COMPLETE.

After this the invoice will stay at Unpaid status without making invoice as paid and adding transaction.

WHMCS Version: 8.7.3

I got next logs rom tblerror_log.

message:
Argument 1 passed to WHMCS\TransientData::retrieveByData() must be of the type string, null given, called in /home/user/public_html/modules/gateways/callback/bp.php on line 0

filename:
vendor/whmcs/whmcs-foundation/lib/TransientData.php

details:
#0 /home/user/public_html/modules/gateways/callback/bp.php(0): WHMCS\TransientData->retrieveByData()
#1 {main}

I have no ideea what is happening and where sto start to solve this issue.

 

Thank you!
