[0.76] AccessibilityValue in View throws exception: "Exception in HostFunction: Loss of precision during arithmetic conversion: (long) " #47635

vincicat · 2024-11-15T15:31:28Z

Description

Similar to react-native-elements/react-native-elements#3955 Sharcoux/slider#102 callstack/react-native-paper#4544, when any non-zero value is given to AccessibilityValue.now on Android & iOS, conversion occurs and an exception will be thrown.

(remark: Using Math.round() to avoid any (long) value will fix the issue temporarily.)

Both Expo (0.52) and bare React Native App (0.76.1 + SDK 34, 0.76.2 + SDK 35) can reproduce the bug. Expo 0.51 will not, so it is very likely related to New Architecture.

Same issue found in iOS 18 in some cases, but expo demo can show that

Steps to reproduce

go to demo
switch to Android/iOS and make sure expo == 0.52
click "Start Progress" to see the crash

Tip

Newer version available: You are on a supported minor version, but it looks like there's a newer patch available - 0.76.2. Please upgrade to the highest patch for your minor or latest and verify if the issue persists (alternatively, create a new project and repro the issue in it). If it does not repro, please let us know so we can close out this issue. This helps us ensure we are looking at issues that still exist in the most recent releases.

I have the same issue on iOS too.

okanisildar · 2024-11-19T18:09:34Z

I also have this issue on iOS. Math.round() is not even a temporary solution if you need a value to be between 0 and 1 like my use case.

DominicWrege · 2024-11-19T18:27:48Z

I am using the @react-native-picker/picker which causes the crash.

updated to 0.76.2, issue remains

vincicat · 2024-11-20T14:15:46Z

@DominicWrege @okanisildar
Sorry to hear that but I don't have that issue on iOS, see if you can isolate the issue with an expo snack demo for iOS

zbynekjadrnicek · 2024-11-21T11:07:58Z

I have the same error after update to SDK 52. I use ProgressBar from react native paper and when I set its progress ratio to decimals, like 0.123, it throws error. But progress=1 works well.

okanisildar · 2024-11-21T19:15:03Z

@vincicat you can check this expo snack.

DominicWrege · 2024-11-21T21:05:01Z

@vincicat

The floating-point item font size causes the crash in my case.

Snack example

Thank you.
I think your case should open another ticket in the library to see if that is the library issue (*very likely, as it is okay to use floating point number in style by changing font size in other component of the snack...)

vincicat · 2024-11-22T14:08:56Z

@vincicat you can check this expo snack.

Thank you so much.

Can confirm that issue occurs on iOS too.
see if react-native-elements/react-native-elements#3955 can help

vincicat · 2024-11-22T14:20:44Z

@react-native-bot can you add the label "Platform:iOS" into that issue?

thonymv · 2024-11-22T20:42:19Z

I'm getting the same error in RN 0.76.3, caused by inserting a float into AccessibilityValue.now in the LinearProgress component's source code of the react-native-elements library.

functionzz · 2024-11-23T06:06:03Z

I'm getting the same issue via implementation of a ProgressBar from 'react-native-paper'.

Older versions like 4.12.6 and newer versions like 5.12.5 both have the same problem.

That is an approach 👍.
With 0.75 it worked. Maybe its a combination of booth. Our I am holding it the wrong way.

dnhan1707 · 2024-11-27T20:52:28Z

hi @vincicat , does this issue happen in other versions as well??

dnhan1707 · 2024-11-27T21:44:04Z

For this issue, the LinearProgress is using accessibilityValue which have to be integer

So you may want to use other library.
React Native recommends to use other community packages

Here is the link:

vincicat · 2024-11-28T19:39:19Z

hi @vincicat , does this issue happen in other versions as well??

thanks @dnhan1707
I can confirm that we are good when using RN 0.75 and older (as old as 0.70) on the Android & iOS when NewArch is disabled
so this is a surprise that the doc said this should be an integer starting from RN 0.70...

Workaround for users of ProgressBar from 'react-native-paper':

- <ProgressBar progress={skinnyHtmlDownloadPercentage} color={MD3Colors.neutral30} />
+ <ProgressBar animatedValue={skinnyHtmlDownloadPercentage} color={MD3Colors.neutral30} />

This works, thank you!

dnhan1707 · 2024-12-09T23:33:07Z

The workaround fix would be removing the now: clamp(value) or we can set it to now: 0 in the LinearProgress.js
I already tested it and work well
