I've written a script that gets an image url from a cell in Google Sheets and adds that image to a template in Google Docs. However, when the cell is empty, the script crashes:
var beforePhoto1 = UrlFetchApp.fetch(row[14]).getBlob();
Really new to programming and would appreciate anyones help as to how to prevent the above code from crashing in the event a cell is empty
Usually there are two options:
if (row[14] != '') {
var beforePhoto1 = UrlFetchApp.fetch(row[14]).getBlob();
} else {
console.log('row[14] was empty');
var beforePhoto1 = 'default_value';
}
// rest code
try/catch:try {
var beforePhoto1 UrlFetchApp.fetch(row[14]).getBlob();
} catch(e) {
console.log('row[14] was empty');
var var beforePhoto1 = 'default_value';
}
// rest code
