Does you static page shows correctly ?

1 - If your static page is in the parent folder, get rid of the first slash

res.sendFile(path.join(__dirname + '../static-pages/journey-analize-report/index.html'))

2 - to serve jquery script in your static file you could define a personnalized path in place of node_module folder

Replace:

app.use('/node_modules/jquery/dist', express.static(path.join(__dirname, '../node_modules/jquery/dist')))

With

app.use('/js', express.static(path.join(__dirname, '../node_modules/jquery/dist')))

and in your html file require jquery with personnalized path

<script src="/js/jquery.min.js"></script>

3 - if the error still exist, comment app.use functions and jquery script in static page. Reload the server to see if its work
