Within the last week there seems to have been a change in the nodejs server environment, by the look of it.
When attempting to load a local json data file I get:
No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://localeventsapp-fredzeppelin.c9users.io’ is therefore not allowed access. The response had HTTP status code 503.
I guess there may be some overlap with Cannot access C9 due to CORS problems
I can get round it by loading the data into a source file, ideally I’d prefer not to do this!
I’ll answer my own qn in case this bites somebody else:
Check your event url!
