I have just downloaded the latest exe from https://github.com/monta-app/ocpp-emulator/releases/tag/v2.3.1

Whenever I click on "Stop transaction" the application just crashes.

Here is my chargers details:

Hm, I can't reproduce this (on Windows 10).
Are there any error messages or stack traces in the application.log file (in /monta directory) you can share?

If instead of pressing the "Stop transaction" button you go from "Ready" to "Unplugged", does it also crash?

Thanks for the reply @gaetjen I can go "ready" to "unplugged" fine.

Where should I find the "monta" directory? I can only find a "OCPPEmulator" directory in c drive:

And no application.log available.

It should be at C:\Users\<your_username>\monta.

Thanks for the logs, I can actually reproduce this. I didn't realize you were using the functions in the drawer. 🙂

PR for fix here: #8

I also added a little explanation about the functions in the drawer to the readme. The tl;dr is, unless you're specifically trying to replicate buggy behavior, you'll usually be better off controlling the charge point through the normal interface.
Here is the explanation I added:

What's up with the 🤓?

Clicking the icon gives access to "message interception". The primary purpose is to have a high degree of control over which messages are sent and received by the charge point. That way it is possible to replicate potentially buggy behavior or custom implementations in a one-off manner without needing to change the actual programming of the charge point. For "normal operation" of the charge point the standard interface should be sufficient.

Also note that the message interception functions are not hooked up to the internal machinery of the charge point. For example, sending a StopTransaction message will not actually change the state of an ongoing charge to be stopped. That means using these functions also makes it very easy to put the charge point into a state that does not match up with what the CSMS is expecting, which can quickly lead to unexpected behavior.

Great thank you! You can always trust other developers or even users to break your app with the unintended way of using it.
