<![CDATA[How do I add a npm module to the server environment?]]>I want to make the google-palette module available for use with Chart.js. I assumed I would just need to do an "npm install" for the module in the jsreport folder, but my scripts don't seem to be able to find it via require. I have the option "allowLocalFilesAccess" set to true. Any ideas?

I have stopped the server, cleared the logs, and restarted.

jsreport-server@ /var/jsreport-test
└── palette@0.1.1

]]>https://forum.jsreport.net/post/4053https://forum.jsreport.net/post/4053Invalid Date<![CDATA[Reply to How do I add a npm module to the server environment? on Invalid Date]]>The script had an early error check on its parameters that was backward, so it was failing off a legitimate request.

]]>https://forum.jsreport.net/post/4054https://forum.jsreport.net/post/4054Invalid Date<![CDATA[Reply to How do I add a npm module to the server environment? on Invalid Date]]>Also.. wow. so the module is called google-palette. And I installed that. And then I referenced it as the wrong thing in the require statement. Yikes. I need a nap! Thanks for your assistance!
