Hi everyone! Future me, leaving more breadcrumbs of knowledge for others who follow…
As tempting as it may be, do NOT add resources.json or thumbnail.png to your gitignore, both will cause things to break. (tested circa Ignition 8.1.7)
Ignoring resources.json files will cause (sometimes cyclical) thrashing of the project files whenever you sync to a new checkout, but more importantly will totally break the newer method of saving named SQL queries to disk.
Ignoring thumbnail.png files would’ve been nice to avoid putting binaries in git, but the first time you update a server and gain views without those files, your log will be full of lines like this:
Error creating digest for resourceManifest=data/projects/Support/com.inductiveautomation.perspective/views/Page/Monitoring/resource.json, file=thumbnail.png
Error reading data for file thumbnail.png for resource at com.inductiveautomation.perspective/views/Page/Monitoring
###Fatal-An error occurred while reading project resources from disk. Disk-to-memory synchronization will not occur!
I hope that maybe IA can resolve the second and allow Ignition to sync up projects from disk without PNG files, but we’ve gotta leave them in for now.
