Kibana - flexmonster pivot tab is empty

Tried installing pivot-kibana with kibana 7.4.2, when I click to open the tab, nothing shows.
 
this is the complete error log:
flexmonster_pivot:372 Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-SbBSU7MfZFnVMq4PuE/jbBz7pPIfXUTYDrdHl7Ckchc='), or a nonce ('nonce-...') is required to enable inline execution.
bootstrap.js:9 ^ A single error about an inline script not firing due to content security policy is expected!
