Do below steps to resolve the issue
-----
There must have been a change in the Build Process in the past month of September, as all of my old apps now fail.
Fix for this ended up being a re-build of the package.json and Gruntfile.js
Gruntfile.js
module.exports
= function(grunt) {
'use
strict';
grunt.loadNpmTasks('@sap/grunt-sapui5-bestpractice-build');
grunt.registerTask('default', [
'lint',
'clean',
'build'
]);};
These settings instruct Grunt to load the plugin that provides tasks for building SAPUI5 applications and running the tasks in the specified order.
package.json
{
"name": "grunt-build",
"version": "0.0.1",
"description": "Grunt build",
"private": true, "devDependencies":
{
"@sap/grunt-sapui5-bestpractice-build": "1.3.62"
}}
Then one additional line had to be added to the package.json as per this SAP Note: https://launchpad.support.sap.com/#/notes/0002801814
So the Package.Json now looks like this:
{
"name": "grunt-build",
"version": "0.0.1",
"description": "Grunt build",
"private": true,
"devDependencies": {
"@sap/grunt-sapui5-bestpractice-build": "1.3.62",
"vscode-uri": "1.0.6"
}
}
