warning: nr_php_get_environment_variables: Unable to access environmental variables on 10.1.0.313 – newrelic/newrelic-php-agent

After upgrading to New Relic Version 10.1.0.313 (from 9.21.0.311) I am getting constant warning logs in the php agent log:

2022-09-22 15:35:52.417 +0300 (50083 50083) warning: nr_php_get_environment_variables: Unable to access environmental variables.
2022-09-22 15:35:54.420 +0300 (50089 50089) warning: nr_php_get_environment_variables: Unable to access environmental variables.

PHP version 8.0.23.

Is there something wrong with my php and/or NR extension ini settings I need to look at/change?
