CSP header issues with eval()

I am developing a site, which is still local. I installed this package to add the correct CSP to my site (which I built with Laravel & VueJs).

I have solved them one by one. But now in my chrome console, I don't see any CSP errors anymore. It only shows a blank page. I opened the site in Firefox. There, in the console, I came across the following error:

Content Security Policy: The page’s settings blocked the loading of a resource at self (“script-src”). Source: call to eval() or related function blocked by CSP.

I searched the generated bundles for the eval() function, but it doesn't appear in any of the files. Does anyone here have some suggestions for me on how to solve this?
