EvalError while ‘unsafe-eval’ disallowed by CSP

Hi,

Ninja Form throws EvalError while ‘unsafe-eval’ disallowed by Content Security Policy.

Content-Security-Policy:
Header set Content-Security-Policy: "default-src 'self'; img-src 'self' data:; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline'; font-src 'self' data:; base-uri 'none'; frame-ancestors 'none'; form-action 'self'; block-all-mixed-content"

Error on all pages with Ninja Form added.

[Error] EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'unsafe-inline'".

I don’t want to use ‘unsafe-eval’. Is there a way to get the form working without touching the CSP?

Thanks,
