Error error : PHP message: Uncaught PHP Exception TypeError

Problem/Motivation

I updated my site to 2.0.3 and I got this error:

[proxy_fcgi:error] [pid 3225696:tid 3226004] [remote x.x.x.x:50262] AH01071: Got error 'PHP message: Uncaught PHP Exception TypeError: "Drupal\\views_cumulative_field\\Plugin\\views\\field\\CumulativeField::getRelationshipEntity(): Argument #1 ($values) must be of type array, Drupal\\views\\ResultRow given, called in /public_html/modules/contrib/views_cumulative_field/src/Plugin/views/field/CumulativeField.php on line 216" at /public_html/modules/contrib/views_cumulative_field/src/Plugin/views/field/CumulativeField.php line 170', referer: https://xx.xx.com/xx/xx/edit

Once I downgraded to 2.0.2, that problem is gone.

Steps to reproduce

Update to version 2.0.3 and error appear.
