open failed: EACCES (Permission denied)

I try to transfer document files (pdf,docx,...), and it's ok with API < 29. But now I always get 'open failed: EACCES (Permission denied)' when trying it on API >= 29

Here is my code:

window.resolveLocalFileSystemURL(fpath, (entry) => {
let options = new FileUploadOptions();
options.httpMethod = 'POST';
options.fileKey = 'file';
options.fileName = entry.name;
options.mimeType = entry.type;
options.params = {
id: 1
};

let fileTransfer = new FileTransfer();
fileTransfer.upload(entry.nativeURL, 'http://localhost/upload.php', (suc) => {
console.log(suc)
}, error => console.log(error), options);

}, error => console.log(error));

Start with the provided resolveLocalFileSystemURL and FileTransfer.upload calls, reproducing the EACCES failure on Android API 29 or later. Inspect the plugin's Android implementation and determine the relevant file-access path; done means document uploads work on API 29+ without breaking the API <29 behavior.
