[BUG] SyntaxError: Named export 'Queue' not found. The requested module 'mnemonist' is a CommonJS module about e-mobility-charging-stations-simulator HOT 11 CLOSED

If the error is only related to the pnpm build command, then the issue is related to your local node.js setup. The CI builds for node.js 16 is successful.
If not, you can try:

import Queue from 'mnemonist/queue.js'

from e-mobility-charging-stations-simulator.

Further down, the ending error is this.

At the beginning of the install, I also get two warnings. I don't know if they're important.

that import - is it in

Not sure what could be wrong with my node.js setup. It's a fresh install on a fresh server. Any ideas/suggestions?

I just gave you the import syntax to test in the previous comment ...

Probably also:

import LRUCache from 'mnemonist/lru-map-with-delete.js' in another file.

from e-mobility-charging-stations-simulator.

Could you please confirm or infirm that the import syntax changes makes the simulator works with node.js 16.x?

If yes, I will integrate the changes.

Hi
I'm not sure what's going on. I started again and downloaded the last release as zipped source code and tried that - instead of doing git clone.

The import queue error does not happen because that line in not in the AsyncLock.ts file in the release file.

I made a video of the install process. See here

The install works, though there are warnings, and on pnpm start the server starts. But then it stops after about 90 seconds.

See screenshots.

The README.md explicitly state that idtags.json must be created from its template.

And as a rule: first test locally and once it's working, go for a remote install.

from e-mobility-charging-stations-simulator.

I edited the idtags.json as you suggested.

The server starts, but never connects to anything. THe old software ran perfectly. And is running perfectly. So I think I'll leave this one.

Oh, on the install instructions, you might consider adding all the missing bits like needing to install husky (and how) and having to install corepack, etc. We're not all into Node.

The install instructions in the README.md already contains all that bits. Would you mind to read it?

It's a configuration issue on your side in config.json or charging station templates. And it's out of the scope of the GitHub issues coverage which are dedicated to development, not end-user support on how OCPP works, how to configure an OCPP server URL, what is a client/server paradigm, how to use Insomnia, etc. for obvious lack of bandwidth available to do it.
