File – Error code 5, encoding_err

image = cordova.file.applicationDirectory + "www/img/deck/" + card.image; 
 file_path = cordova.file. documentsDirectory + "wisdom.png";
 $cordovaFile.createFile(file_path, true).then(function(result) {
 alert(JSON.stringify(result));
 }, function (err) {
 alert('create error: '+ JSON.stringify(err));
 }); 
 $cordovaFile.writeFile(file_path, image).then(function(result ) {
 alert(JSON.stringify(result));
 }, function(error) {
 alert(JSON.stringify(err));
 }); 
When creating the file, this will give error code 5, ENCODING_ERR. Writing the file will not give a success or failure error. There is no image in the gallery. What should be the path to save the file? How should I send the image to the write method? Why do I receive an encoding error? 
 

I want to save the image from the ios application to the gallery so that users can share it.

< p>My application uses ionic framework & ngCordova. I want to save images like this:

image = cordova.file.applicationDirectory + "www/img/deck/" + card .image; 
 file_path = cordova.file.documentsDirectory + "wisdom.png";
 $cordovaFile.createFile(file_path, true).then(function(result) {
 alert(JSON. stringify(result));
 }, function(err) {
 alert('create error: '+ JSON.stringify(err));
 }); 
 $cordovaFile .writeFile(file_path, image).then(function(result) {
 alert(JSON.stringify(result));
 }, function(error) {
 alert(JSON.stringify(err));
 });

When creating the file, this will give error code 5, ENCODING_ERR. Writing a file will not give a success or failure error. There is no image in the gallery. What should be the path to save the file? How should I send the image to the write method? Why do I receive an encoding error?

I encountered the same error and have found a solution. You may no longer need it, but someone is looking for it.

Add the following line to the configuration:

File URL should also start with file: ///...
