Hi @prasanta303 , I hope you are on Windows. This issue is fixed in ibm_db version 1.0.2. Can you please modify your package.json to include the latest version and try again. "ibm_db": "1.0.2", Please let me know how it goes. Thank you.

Hi @prsahoo, Yes, I am on Windows. I have modified my package.json as per your advice. Even if, I am getting same kind of issue but have different version mismatch as below,

@prasanta303 I managed to get this to work - I changed the Package file - Jade was deprecated and you need Pug "dependencies": { "cf-deployment-tracker-client": "0.0.8", "express": "3.5.x", "ibm_db": "1.0.2", "pug": "2.0.0-beta11" }, Refresh your package file and rerun npm install.

Not sure it's relevant but I also updated the Manifest File to have my own unique host variable below with your own unique one

Error: Module version mismatch. Expected 47, got 46.

This is because you installed your dependencies with one node version, and are requiring them with another node version.

47 is node 5.x and 46 is node 4.x, FYI: node -p process.versions.modules will tell you the ABI number for your node.
