I have just tried the boilerplate out the first time, and I am moving from route to another route, at default it moves to the route, but if CTRL + R is clicked it shows cannot get error with the route link.
The following error is been shown in the console
Refused to execute inline script because it violates the following Content Security Policy directive: "default-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-vdjZcosZlrT8RbIl66uL4P8KawZHjNSV+bVC3gpYylg='), or a nonce ('nonce-...') is required to enable inline execution. Note also that 'script-src' was not explicitly set, so 'default-src' is used as a fallback.

How did you fix this issue, Am having the same issue
I noticed i was using history mode in my routing instead of using hash bang mode so i changed it back to using hash mode
3 hours stucked in this issue, now I have some closure.
It isn't specified in the documentation? It is really simple, but messed up error
