Error when installing on docker node-red-contrib-db2 and node-red-contrib-db2-fixed

General

All,

When I am trying to install on my docker image of node-RED node-red-contrib-db2 or node-red-contrib-db2-fixed I was initially having an error around " ReferenceError: primordials is not defined". I was able to resolve that by following the suggestions here to change the package.json file (instructions under using npm around overrides & preinstall scripts). After that, when I try the install I get the following error:

~ $ npm install node-red-contrib-db2

Any ideas? I tried to ping the IP 129.35.224.112 from docker terminal and seems to be OK but if I try to go to the webpage mentioned in the errors from my local computer it doesn't seem to work so I wonder if something is off that is not allowing to download the .tar.gz

Welcome to the forums @pferreira

I'll be honest with you, both the packages you have tried have not been updated in 5 years.
and you're having to resort to fixing them yourself.

One of the nodes have a PR, to update the driver version, dated 2019, and one with an unanswered issue back in 2018

Clearly it would seem these nodes do not see any maintenance, and are likely using URIs that have since been updated. :man_shrugging:

I know nothing about db2 (and 5 years may not be anything with db2 developments), so my advice may be invalid, but I would try different nodes, that have been updated more recently.

Library - Node-RED (nodered.org)

Thanks @marcus-j-davies. Unfortunately, I do not see any other package related with DB2 integration which is what I'm trying to achieve.

Are there any further ideas from the community here?
