I use mergeJSON to move back an forth between json and arrays for web services. It’s currently failing when I fetch json data from another source on the Ubuntu server, while the same code and data works on MacoS - presumably due to some encoding issues.
It’s a large amount of data and I can’t debug where the issue is easily. Maybe I can use jsonImport/Export on the server? Not sure. Any thoughts?
