Simple enough turbo app.
Everything works on 16.4 and after.
On 16.2 and 16.3, 15.5 the view load fails without logging any error, displaying a warning window containing a very nicely designed blue warning triangle, “Error loading page”, “The page could not be loaded due to a configuration error”. It doesn’t seem to matter what URL it tries to load.
Is this something known, or have I screwed something up? Can’t think of a search that yields anything useful.
Demo app is doing the same.
Encountered the same problem. I was trying to get screenshots for app release on older/smaller devices and found this exact issue.
Solution is to add the esm shims. It was an upgraded app so they didn’t get included automatically.
Hey! what made you look at ESM specifically? Was there any specific debugging step that pointed you in that direction? Several users have reported the error, but I have not been able to replicate it 
Happy new year
