Describe the problem
I have an n8n instance running in docker. I added a few npm packages to try out if they work normally.
Here is my command for adding the packages in the docker:
RUN npm install -g mongodb mysql apexcharts markdown-it markdown-parser pdf-parser pdfjs redis exceljs
All the npm packages can be found inside the image that gets created, but when I go into n8n, a few of them don’t work as I expect them. For example if I call the mongodb package it works fine.
But if I call exceljs it returns an error.
It is clear that the npm package gets recognized, because you can see it in the stack trace. Another type of error I get is with pdf-parser.
When I tried these same packages in a normal js file outside of n8n, they ran fine.
So my question would be if there is something that defines what npm packages can be added to n8n? Is there a workaround to adding these packages?
Please share your workflow
