Automated test 'Cypress' gives error on OutsystemUI.MWO.js

During the automated test, the test tool 'Cypress' gives the next error:

The following error originated from your application code, not from Cypress. It was caused by an unhandled promise rejection.\n\n > Error adding script '/<application>/scripts/OutSystemsUI.MWO.js?fZcFt60k3mJDWeENwt0Gbg' to document 'https://<environment>/<application>/<page>'. No retries left. 

This happens after updating OutsystemsUI to Version 2.15.0.

Did anyone else have this problem? And if so, did anyone succeed to solve this?
