UnCaught FileTransferError?

I am trying to open a PDF in my ionic application and from my server I am receiving a status code 200 which means it is successfully receiving the data in order to open the PDF.

However, I am receiving this error:

I have been assured that this is not a problem with our API and is a runtime error but this has been working in the past and Im unsure what this error is telling me.

Here is my function to get and open the pdf:

     const loading = await this.loadingController.create({
       message: 'Loading ' + msg + ' report...'
     });

     await loading.present();

     // Get Access token from storage

     this.storage.get(ACCESS_TOKEN).then(token => {
       console.log('token from storage: ', token);

       const urlOrderNo = this.apiUrl + pathExtension + ID;
       console.log(urlOrderNo);

       this.nativeHttp.get(urlOrderNo, {}, { Authorization: 'Bearer ' + token})
       .then(data => {
         console.log('status: ', data.status);
         console.log('data: ', data.data); // data from server

         loading.dismiss();

         if (data.status === 200) {

          // Get mobile platform
          if (this.platform.is('android')) {

            const uri = encodeURI(urlOrderNo);
            const path = this.file.dataDirectory;
            const transfer = this.ft.create();

            transfer.download(uri, path + 'file.pdf', false,
            {headers: { Authorization: 'Bearer ' + token}})
          .then ( entry => {
            const url = entry.toURL();
            loading.dismiss();
            console.log('url: ' + url);
            this.fileOpener
            .open(url, 'application/pdf')
            .then(() => console.log('File is opened'))
            .catch(e => console.log('Error opening file', e));
          })
          .then(error => {
            console.log(error);
          });

          } else if (this.platform.is('ios')) {

            const uri = encodeURI(urlOrderNo);
            const path = this.file.documentsDirectory;
            const transfer = this.ft.create();
            const setName = Date.now();

            transfer.download(uri, path + `${setName}.pdf`, false,
            {headers: { Authorization: 'Bearer ' + token}})
          .then ( entry => {
            const url = entry.toURL();
            loading.dismiss();
            console.log('url: ' + url);
            this.fileOpener
            .open(url, 'application/pdf')
            .then(() => console.log('File is opened'))
            .catch(e => console.log('Error opening file', e));
          })
          .then(error => {
            console.log(error);
          });

           }
