Hi,
I tried an app restart and even Homey restart… The images remain accessible when using Persistent Storage - Homey Apps SDK links.
Only after uninstalling/re-installing the app the image was gone and http://192.168.178.72/app/nl.mennovanhout.insights-graphs/userdata/graph.png.png returns “Cannot GET /app/nl.mennovanhout.insights-graphs/userdata/graph.png.png”
Are you sure that reboots should do the the trick? At least for me that’s reproducable having it done twice (with Shift-Reload, of course).
Uninstall however yields: http://192.168.178.72/app/nl.mennovanhout.insights-graphs/userdata/graph.png.png “Not Found: App with ID nl.mennovanhout.insights-graphs”, followed by reinstall intermediate “App Not Ready”, followed by “Cannot GET /app/nl.mennovanhout.insights-graphs/userdata/graph.png.png” and finally after re-running the flow to create graph.png (or graph.png.png) finally shows the png in the browser.
Not really a big deal when overwriting images, but at least good to know if the filenames are created uniquely.
Regards,
Michael
