SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data

On RHEL7.6 (Gnome 3.28) the latest version of comnection manager does not load:

2019-05-08T10:00:49.637228+02:00 bn2lts101 journal: Extension
"[email protected]" had error: SyntaxError: JSON.parse:
unexpected character at line 1 column 2 of the JSON data

Which JSON data could that be? How to debug the issue?

For my Gnome (3.28.3 on Centos 7) the error appears in file extension.js, Line 113
To Fix:
Change:
let jsondata = JSON.parse(ByteArray.toString(filedata[1]));
To:
let jsondata = JSON.parse(filedata[1]);

Restart Gnome afterwards (Alt+F2, r); I also had to delete my config file ~/.connmgr
