Error in firebase.mlkit.useCustomModel: TypeError: Cannot read property 'trim' of undefined

Hi. I’m trying to get the MLKit reading my model and the labels for it.

I’ve tried with the Vue Component, but it doesn’t allow to load the component. Then I loaded the still image using the camera. Here’s the method that wants to apply the custom model:

import { MLKitCustomModelResult, useCustomModel } from "nativescript-plugin-firebase/mlkit/custommodel";

useCustomModel({
      image: this.image,
      localModelFile: '~/custommodel/rust.tflite',
      labelsFile: '~/custommodel/rust_labels.txt',
      modelInput: [{
        shape: [1, 299, 299, 3],
        type: 'QUANT',
      }],
    })
      .then((result: MLKitCustomModelResult) => console.log(JSON.stringify(result.result)))
      .catch(console.error)

I’m always getting this:

JS: 'Error in firebase.mlkit.useCustomModel: TypeError: Cannot read property \'trim\' of undefined'
JS: TypeError: Cannot read property 'trim' of undefined

I think it is not able to read the file contents. I also checked in the demo-ng, for still images as well for the cam feed, but it seems to happens also for the

Good point, I’ve added it to the doc: https://github.com/EddyVerbruggen/nativescript-plugin-firebase/blob/master/docs/ML_KIT.md#custom-model-inference

Hey Eddy… I took a look on my repo. I actually was not copying correctly the tflite file nor the txt file. I included both in the webpack config and at that point it didn’t work. I deleted the platforms and node_modules folders and restarted again. After that it recognized the model and I could use my own model.

I guess it’d worth including that instruction in the repo.

Anyways… thank you very much for your help.
