Uncaught SyntaxError: Unexpected token < in JSON at position 4

[#1]

I have an AEM 6.4 project that works fine in the local environment, but on deployment to the enterprise AEM 6.4 environment, I can no longer delete components in a page, or even move them, images used in components do not show up in dialog and so on.

I see the following errors in the browser console:

I am clueless as to why this could be happening.

Any help on this would be great to move forward.

Are you using Resource Override or any other plugin to inject js?

It seems the error is from locally injected js.
