HI All,

I have added offline button in Field service mobile App Service order entity.

And on click of that button I am trying to download the word file which I have generated using Power automate flow. But it does not download the file, well it works in web field service.

Please help me with solution as I am stuck.

Our code for reference:

Serviceorder.prototype.downloadWordFile = function (fileBody, fileName) {                var byteCharacters = atob(fileBody);                //@ts-ignore                Xrm.Utility.closeProgressIndicator();                var byteNumbers = new Array(byteCharacters.length);                for (var i = 0; i < byteCharacters.length; i++) {                    byteNumbers[i] = byteCharacters.charCodeAt(i);                }                var byteArray = new Uint8Array(byteNumbers);                var blob = new Blob([byteArray], { type: 'application/pdf' });                var link = document.createElement('a');                link.href = URL.createObjectURL(blob);                link.download = fileName;                link.click();            };            return Serviceorder;        }());

Thanks,

Hi,

Our team analyzed your code and found two errors in it.

First, according to your requirement, you want to download a WORD document, but the content type specified in the code is "application/pdf", which applies to PDF files, not Word files. To download Word files, you should set the correct content type.

Secondly, is the code you shared the complete code? Our team found a syntax error when we tried to analyze your code.

So, we can only try to analyze the download function, the following is the improved code of our team.

Serviceorder.prototype.downloadWordFile = function(fileBody, fileName) { // Decode the Base64-encoded file content into binary data var byteCharacters = atob(fileBody); // Create a Uint8Array array to store the file content var byteArray = new Uint8Array(byteCharacters.length); for (var i = 0; i < byteCharacters.length; i++) { byteArray[i] = byteCharacters.charCodeAt(i); } // Create a Blob object with the correct content type var blob = new Blob([byteArray], { type: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document' }); // Create a link element var link = document.createElement('a'); link.href = URL.createObjectURL(blob); // Set the file name for the download link.download = fileName; // Add error handling var errorHandler = function() { console.error('Unable to download the file.'); }; // Asynchronously trigger the file download if (navigator.msSaveBlob) { // For IE11 and Edge browsers navigator.msSaveBlob(blob, fileName); } else { link.style.display = 'none'; // Hide the link element document.body.appendChild(link); // Add the link element to the page link.click(); // Trigger the click event to start the file download document.body.removeChild(link); // Remove the link element after the download is complete } };

So, would it be convenient for you to provide the complete code, as this will enable our team to pinpoint your problem faster and come up with a solution faster and more efficiently.

I hope my answer is helpful to you! If you have any other questions, please feel free to contact me.

Best Regards,
