Input password field set value fails

Hello!

I’m new to vaadin-testbench and I’m trying to automate a login into a website but when I set user and password using vaadin test it says that the credentials are wrong but if I copy the credentials used in the test and paste them manually into the login form I can log in without any problem. Any idea why this can be happening?

Thanks in advance

What version of Vaadin and Testbench are you using?
If you check the full stack apps in https://vaadin.com/start they all have login view and testbench tests doing the login.
