Hi @alabiboo the same code is working for me. Anyways I tried a alternative for you, kindly have a look at below.

1. Install File plugin from here > https://ionicframework.com/docs/native/file/
2. let base64PDF = await this.file.readAsDataURL(pdfFilePath, pdfFilename);

This also worked for me. Let me know your feedback.
