Could not invoke BlinkCardAndroid.scanWithCamera about blinkcard-react-native

[mparadina]

Hi @KevinToh0329 as the inquiry was resolved directly, I am closing the issue.

The issue with the 2.9.1 version was connected to compatibility issues with React-Native.
The version used in the project is 0.59.0, while the version used to build and test the latest SDK is 0.72.6.

The issue with the 2.6.0 version was related to anonymizing the card information, which was fixed in the 2.9.0 version.

Hi @KevinToh0329

Just to double-check, are you using the BlinkCard SDK on a simulator or a physical device?
The SDK is not supported for running on simulators.

When does the exception occur?
When initializing the SDK, during the scanning process, or when you handle the scanned results?

Hi @mparadina ,
Thanks for the quick response.

It's on a Physical Device.

The exception occur when this line of code run.

await BlinkCardReactNative.BlinkCard.scanWithCamera(
    new BlinkCardReactNative.BlinkCardOverlaySettings(),
    new BlinkCardReactNative.RecognizerCollection([recognizer]),
    licenseKey
)

Which I guess is during initializing the SDK, right before scanning process.. Because the camera didn't appear at all.

@KevinToh0329 thank you for the feedback.

Have you used the BlinkCard SDK before and it was working as expected?
This code looks correctly implemented.

Just to double-check, when you obtained the SDK, do you have Git LFS installed?
It is required to correctly obtain the BlinkCard framework.

Lastly, is the issue occurring with our sample application? You only need to git clone this repo, enter it, and run the ./initReactNativeSampleApp.sh script via Terminal.

Hi @mparadina ,
The BlinkCard SDK was working fine before. We installed this SDK for years.

I uses npm i. because the package already marked in the package.json.

    "@microblink/blinkcard-react-native": "^2.4.1",

and inside package-lock.json

    "@microblink/blinkcard-react-native": {
      "version": "2.9.0",
      "resolved": "https://registry.npmjs.org/@microblink/blinkcard-react-native/-/blinkcard-react-native-2.9.0.tgz",
      "integrity": "sha512-qSP+LP6XQYepATqNqdMxxRCovB/zGG8xPv61rV2gtpU7jPFKe1b/K1TnVnkCmyEmRIm5htzSbmzgHyG2QxZ8Yw=="
    },

After recent deployment to production, we faces the issue where the APP crashes when the user click on the Card OCR.

Hi @KevinToh0329

We've released BlinkCard 2.9.1 in the meantime. Can you try obtaining it and seeing the issue persists?
You can just run the command: npm install --save @microblink/blinkcard-react-native

Please try this out and let me know if it helped.

Hi again,

When I try to install older version. I'm hitting this error. And there's no additional logs to check with it.

Hi @KevinToh0329

When you try installing the sample application with BlinkCard 2.9.1, are you getting the exact same local variable exceptions? I tried reproducing the same behavior on my end but with no luck.

Are you maybe able to share a minimal reproduction sample so that we can try to reproduce it on our end?
