Errors:

know errors and how to tackle them

1. [object Promise]: This error is related to the promise. It will occur in two cases: i). if the uploaded files are not in a DICOM format and ii). user uploads file more than they were supposed to. Please always take a look at select the number of inputs: options about how many files you were supposed to upload. If you want to upload two files then please change select the number of inputs: to 2.

2. Uncaught ReferenceError: itk is not defined: This error will occur only if the user device is not connected to the internet. As our visualizer uses the itk.js library to read DICOM files and we are calling the itk.js library from the CDN unpkg server: https://unpkg.com/[email protected]/umd/itk.js and it needs internet to run itk.js.
