Reload not working with unleash edge in offline mode

[DAGRSAG]

Describe the bug

Hi
currently I'm in preparation of creating a new Enterprise Signing with Unleash. For that I'm testing different things.

We are planning to use the Unleash Edge in offline mode for our local development. To make it easy for our developers, I'm working on some scripting.

I have downloaded the latest windows binary from your GitHub repo and started it with the following commands

unleash-edge.exe offline --reload-interval 10 -c u1234e -f uf4321e -b "C:\Dev\toggles.json"

The parameter c, f and b works as expected. Unfortunately the most important one (r or reload-interval) not. I have the following toggle defined

{
  "SR27_Pack": {
    "enabled": false
  }
}

Initially the toggle is false, which is expected. Then I've changed the value for enabled to true. But even after some minutes, the toggle is still false.

I also have tested with the environment variable RELOAD_INTERVAL. This have the same issue. Environment variable for workers works.

Where is my issue? Can you provide me feedback please or is it an issue?

Steps to reproduce the bug

1. Start the unleash edge in offline mode (command see above)
2. Switch a toggle value from false to true

Expected behavior

The toggle state should be changed from false to true

Logs, error output, etc.

No response

Additional context

What is also odd to me is, that the endpoint internal-backstage/tokens returns 500 and the message Requested application data is not configured correctly. View/enable debug logs for more details.

But no message gets logged.

Unleash version

19.6.2

Subscription type

None

Hosting type

SDK information (language and version)

I have tested it with a Windows shell and Windows PowerShell

Hi @DAGRSAG . Thanks for reporting this.
You might've run into some windows path issues; I'll see if I can't reproduce.

For the /internal-backstage/tokens endpoint. It will not work in offline mode, since there is no TokenValidator available in offline mode, that's why you're getting the 500. We just haven't seen the need for this endpoint in offline mode.

Hi @DAGRSAG . I was wrong. This seems to have been an oversight when we added support for client/frontend tokens to offline mode. We no longer have tokens to refresh. I'll release a patch later today where this should work again. I'll also see if I can't find a way to make the /tokens endpoint be useful in offline mode.

Again, thanks for reporting, and sorry for the mixup, we don't test much on Windows, so my gut reaction was that I was sure I'd seen it work on Linux so it might be a Windows issue. I'll get it working on both platforms before releasing the patch.

This is fine for me. Just from the documentation my expectation was that this endpoint is also available in offline mode

[DAGRSAG]

I'll release a patch later today where this should work again

That would really be awesome if there is a fix in place. Because for the POC to present it, it would be good to have a working environment

I'll also see if I can't find a way to make the /tokens endpoint be useful in offline mode.

As mention already. If there is one ok, but at least from my point of view, the reload stuff is the absolute important one

19.6.3 released with this fix in place. Again, thanks for the good report. Enjoy your weekend

[DAGRSAG]

Yes can confirm, that both things now working. Thanks for the quick response and fix. Awesome. Have a nice weekend
