I am using postman to get OAUTH2 token from the cuba server.
But i am getting error as "Failed to load the bootstrap javascript: ./VAADIN/vaadinBootstrap.js?v=8.6.4-17-cuba "
I was trying to get OAUTH token for the rest API and recieved javascript error both in postman and SOAP UI. In the older version of CUBA i was using {noop} before client.secretkey in the properties file. After upgrading to latest version i started observing javascript error and I solved the problem by removing {noop} before the secret key.
