问题
I am getting the following error in my Angular/Play/Bootstrap application. But I have not added any code which explicitly adds font from the web. How could I find out from where the browser is trying to download the font and from where in the code it is being downloaded?
Refused to load the font 'data:font/woff;base64,d09GRgABAAAAAGVUABEAAAAAxuQAAQABAAAAAAAAAAAAAAAAAAAAAAAAAABHREVGAAABgAAAAC4AAAA0ArgC7UdQT1MAAAGwAAAQ6AAALgxKsqRTR1NVQgAAEpgAAAH3AAAELqI5y+RPUy8yAAAUkAAAAE8AAABgaGyBu2NtYXAAABTgAAABlAAAAkQkRATXY3Z0IAAAFnQAAABeAAAAugDsQf1mcGdtAAAW1AAABZcAAAvNb3/BHGdhc3AAABxsAAAACAAAAAgAAAAQZ2x5ZgAAHHQAAEApAAB3CtbiupxoZWFkAABcoAAAADYAAAA2BkubWWhoZWEAAFzYAAAAIAAAACQHFARfaG10eAAAXPgAAAI6AAAEEk4TN4Nsb2NhAABfNAAAAhIAAAISiLhpam1heHAAAGFIAAAAIAAAACACigzgbmFtZQAAYWgAAACUAAABHhQGLdJwb3N0AABh/AAAAq4AAASRk5y6n3ByZ...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' because it violates the following Content Security Policy directive: "default-src 'self'". Note that 'font-src' was not explicitly set, so 'default-src' is used as a fallback.
