SOLVED - PHP Warning: Undefined variable $product

[sohopros]

VirtueMart 4.0.22 10864 | Joomla 4.3.3
Our error log is filling up  (about 10 lines per minute) with these two entries:
PHP Warning:  Undefined variable $product in public_html/modules/mod_virtuemart_minicart/tmpl/default.php on line 49
PHP Warning:  Trying to access array offset on value of type null in public_html/modules/mod_virtuemart_minicart/tmpl/default.php on line 49

Can anyone suggest a fix?

"mod_virtuemart_minicart" is a 3rd party module. You should contact the module developer.
