[health: 13.1.0] Calling getHealthDataFromTypes with multiple types, when one type does not have permission, throws and does not return any data

[biklas7]

Plugin Name

health

Plugin Version

13.1.0

Device

iPhone 12 Pro

Operating System

18.5

Describe the bug

getHealthDataFromTypes supports a list of HealthDataType to read from, but if at least one of the given types doesn't have user permission, the whole function throws and does not return any results, even though it got results from the other given types that the user gave permission for.

Steps to Reproduce

1. Set up Apple Health so the app has read permission for HealthDataType.BLOOD_GLUCOSE but not for HealthDataType.INSULIN_DELIVERY.
2. Make sure you have data on Apple Health for those types, if not, add some mock data.
3. Call getHealthDataFromTypes with types: [HealthDataType.BLOOD_GLUCOSE, HealthDataType.INSULIN_DELIVERY]
4. Notice that it will be able to get that for HealthDataType.BLOOD_GLUCOSE
5. But then will throw when trying to read HealthDataType.INSULIN_DELIVERY
6. And all the data is lost

Expected Behavior

It should catch the throw and return the data from HealthDataType.BLOOD_GLUCOSE or, in more general terms, that function should not throw if it was able to get data for at least one type, because otherwise it's just throwing data away and we could argue that if that's the intended behavior, then it should not accept a list required List<HealthDataType> types.

Actual Behavior

It throws and tosses all the data, even though it was able to read from the types that it had permission for.

I just tried the example app without giving permission to some values, but the get and adding health data worked fine. Could it be perhaps your setup that is causing this?

[biklas7]

I don't know what happened, but I thought @iarata left a comment about a missing HKMetadataKeyInsulinDeliveryReason. Maybe it wasn't an issue, so the comment got deleted?

Anyway, I just tested requesting blood glucose and insulin delivery simultaneously, and it throws an authorization error, so I've assumed it was something to do with permissions, because on my test device, I did not set the insulin delivery permission.

After I go to Apple Health and give permission to both, it works.

I've debugged that call, and it's clear that something is causing an authorization error, and since there's no try/catch block in any of the functions called inside getHealthDataFromTypes, it just tosses the glucose data away and bubbles up the exception.

I did not debug the native code, so I don't have much more information. Maybe I can try to request other types just to rule out if the issue is related to a specific type like glucose and/or insulin.

@iarata have you tried to replicate using the exact same types?

[iarata]

@biklas7 Yeah I thought the HKMetadataKeyInsulinDeliveryReason was the reason but no. Still I tested with the same types you mentioned and everything was fine. It just gives error for the types it doesn't have access to and basically skips it. If you could show a screen record of what is happening that would help a lot

[biklas7]

Sure! Thanks for checking, i'll get back with more information 👍

@iarata please check this video.

As you can see it reads the glucose data, but then fails with authorization not determined and throws, causing the glucose data to not be returned.
