Answer 1

I had the same problem ("Manifest: Line: 1, column: 1, Syntax error") while running my app (react app with react-router, published with AWS Amplify).

Source address:


Target address:
/index.html

Type:
200 (Rewrite)

The above solution also fixed problem with non-working react-router links in production as it was reported in the following thread: React Router DOM not working correctly on Amplify Console AWS

Here is to my personal project with fixed manifest.json issue, as well as non-working react-router issue (a link to some random code snippet - fibonacci memoization in this case):
