Hi everyone,

I’m building a Reactive Web App where:

• The user can take a photo using the Camera Plugin (TakePicture action).

• The photo is then converted to Base64 and sent to Google Cloud Vision API for detection.

• The results are displayed and also stored in a PackageHistory UI, where the user can add/view past captures.

So far, I managed to set up the Google Vision API integration and I can send images to it successfully.

1. Camera Action / Base64 Conversion

   • I created local variables LocalImageBinary (Binary Data) and CapturedImageBase64 in TakePictureOnClick (Text).

   • When I try to assign CapturedImageBase64 = BinaryData.BinaryToBase64(LocalImageBinary), I keep getting syntax or “unknown function” errors.

   • Sometimes TakePicture.MediaResult.Thumbnail is not recognized, even though I dragged the TakePicture action into my flow.

2. Feature Not Implemented (Navigation / Add Button)

   • On my Products screen and PackageHistory screen, when I add a button and run the app, I get this error:

     Feature not implemented: Create a new action or navigate to another screen

   • I want the button to either:

     • Trigger my TakePictureOnClick client action, OR

     • Navigate to another screen (e.g., PackageHistoryDetail).

   • But I can’t get it working.

3. PackageHistory Add Button

   • I want to have an “Add” button in my PackageHistory screen where users can add the captured photo + detection results into the history list.

   • Right now I’m not sure how to properly bind the data so that new items get stored and displayed.

   • Any advice on fixing the TakePicture + Base64 assignment, the navigation error, or setting up the PackageHistory Add button would be a huge help 🙏
