Error while trying to use the following icon from the Manifest

Question

While running react app my console always shows this error message. An i know why this is showing?

"Error while trying to use the following icon from the Manifest: http://localhost:3000/favicon.ico (Resource size is not correct - typo in the Manifest?)"

Answer 1

Change sizes in the manifest.json.

Try this:

"sizes": "16x16" 

Answer 2

Go to the index file and comment out <link rel="manifest" href="%PUBLIC_URL%/manifest.json">

Answer 3

I was having the same issue. If you open up your manifest.json located in the public folder of you'll notice a bunch of specifications for icons. If you deleted them when cleaning up your app or added one that does not fit the parameters within the manifest you will get the error you're getting. Edit the "src" within the manifest for your new favicon.ico, or delete the ones your not using and your problem should disappear.
