OpenHAB Cloud Installation erros

[kristofrk]

I am trying to install OpenHAB Cloud on a Ubuntu 24.04 LTS AMI. The 'npm install' command comes up with errors.
First it shows
While resolving: [email protected]
npm ERR! Found: [email protected]
npm ERR! node_modules/bcrypt
npm ERR! bcrypt@"^5.0.1" from the root project
npm ERR!
npm ERR! Could not resolve dependency:

npm ERR! Fix the upstream dependency conflict, or retry

npm ERR!
When I retry with either of the above options, it gives an error for /home/ubuntu/openhab-cloud/node_modules/heapdump
an an exit cod 1 for gyp.
Any suggestions?

I have fixed those problems, but when directing the browser to the IP address of my AMI, I get a 404 error from nginx. I am using the default configuration provided in the installation/customization instructions.

This is the error I am getting:
024/06/17 18:57:55 [error] 449#449: *1 connect() failed (111: Unknown error) while connecting to upstream, client: 73.234.97.133, server: , request: "GET /favicon.ico HTTP/1.1", upstream: "http://127.0.0.1:3000/favicon.ico", host: "52.23.169.119", referrer: "http://52.23.169.119/"
app.js is running (albeit not finding Authkey.p8), the configuration correctly specifies 127.0.0.1:3000.

NGINX is actually showing an internal error.

Similar problem here!

This is my configuration

Debian Bookworm
Python v3.11.2
nodejs v14.21.4

I cloned openhab-cloud v1.0.18 (313390d)

Among some warnings about unmet dependencies of bcrypt and unsupported platform for fsevents, which I haven't resolved yet, I have no idea how to cope with [email protected] and node-gyp failing to rebuild this library for my platform...

@kristofrk How did you solve the problem with heapdump???

@FoxWhiskey I asked ChatGPT to analyze my error messages and followed its suggestions. I am attaching a file.
Clean up heapdump.docx

I also added a resolutions entry to package.json to force resolution for bcrypt-cache.
"resolutions":{
"bcrypt":"^5.0.1"
}

@FoxWhiskey I am also attaching the notes I took concerning my modifications. I got great help from the OpenHAB forum.
OpenHAB and OpenHAB Cloud.docx

I didn't know black magic is allowed to resolve openHAB-cloud installation problems 😉.
Awesome, @kristofrk !! Thanks for your hints.
Actually, I hit slightly different problems, but your documents helped a lot to build openhab-cloud:
it turns out, that not heapdump is the problem, but node-gyp itself...

I will post a summary of my approach ASAP, just in case someone else is interested.
Thanks a lot again!

PS: I was able to get the app running, but cannot tell anything about runtime issues, yet...
