we are seeing what appears to be an internal healthkit error appearing in our app. not sure if it's connected, but we've mostly seen it reported on devices running ios 16. even though our app's primary language is japanese, and in all reported occurrences the app was running in japanese, the error message itself appears in english. searching the error string on the web yields surprisingly few results (including only two mentions on this forum that i could find, neither of which seemed relevant). this would seem to suggest that it's coming from something deep inside healthkit, since the error message is not localized.
in all reported cases, the user had recently upgraded to a new iphone. in most cases, the problem only occurs on the new device even though everything had been working correctly prior to the upgrade. the error occurs when the app is unable to read step count data from healthkit.
we have confirmed that the app has been granted access permissions to all health data via os settings. we've also tried having the user toggling those settings off, then back on, rebooting the device, deleting and reinstalling the app, etc., to no avail.
the error message is "Unable to invalidate interval: no data source avallable."
we'd appreciate it if anyone can shed more light on this issue.
thanks!
