Error parsing JSON: SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data

[jervisliu]

Hi, we started to get following SyntaxError: JSON.parse exception since today or yesterday. As guvnorng depends on errai snapshot, I guess it must be sth introduced in Errai in the last 1 or 2 days. Any ideas?

Thanks,

Jervis

The Errai error popup also shows this message:

An Error Occurred in the Bus

Show further errors
