Hi,  
i have a big Problem with my Visualization. I have ELK 7.3.2  
When i try to open my plugin transform\_vis i get this message:  
[visualization] \> Cannot read property 'appState' of undefined

I get this message in F12

Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' 'nonce-GuO+2I8MzMM6NHHO'". Either the 'unsafe-inline' keyword, a hash ('sha256-SHHSeLc0bp6xt4BoVVyUy+3IbVqp3ujLaR+s+kSP5UI='), or a nonce ('nonce-...') is required to enable inline execution.

What can i do?

Kind regards
