Hi,

Change the manifest code 'qweb': [ "views/receipt.xml",], into assets
In manifest file,

'assets': {

        'web.assets_backend': [
            'module_technical_name/static/src/js/filename.js',
            // path of the particular js file
        ],
        'web.assets_qweb':
            [
                'module_technical_name/static/src/xml/filename.xml',
 
                // path of the particular xml file
            ],

    },
