Troubleshooting: Issue with encoding in Javascript Blob using Ionic file plugin

Could you please help me troubleshoot why this code is not functioning correctly?

Note: file is a native plugin

var blob = new Blob(["This is the content of my blob"], { type: "text/plain" });

    this.file.writeFile(this.file.dataDirectory, 'myletter.txt', blob, { replace: true })
      .then(() => {
        //actions to take upon successful write
      })
      .catch((err) => {
        console.error(err); //error handling here
      });

The exception being thrown is:

FileError
code : 5
message : "ENCODING_ERR"
__proto__  : Object

Answer №1

The problem has been identified here. It was caused by the use of this path this.file.dataDirectory.

Resolution: Replace it with

this.file.externalApplicationStorageDirectory
