Testing now!

[cocoa-xu]

I haven't shipped it yet but I think this should be everything (You can test it by placing the adbc_driver_manager.dll file in priv/bin directory)

[DnOberon]

Seems to work! Thank you so much for your help!

[DnOberon]

I'll keep my eye open for the release so I can switch, thanks again :)

[cocoa-xu]

Going to release v0.7.7 and retire v0.7.4-v0.7.6.

[cocoa-xu]

Okay, v0.7.7 is shipped🤞

[DnOberon]

@cocoa-xu SUCCESS

Feel free to close :)

[cocoa-xu]

That's great to hear! Closing this now

Seeing a new issue, intermittment on prod releases @cocoa-xu

What's odd is that this is on starting the application, where no code from this is actually running afaik. Sometimes it boots up my phoenix server ok, sometimes it gives me this error chain. Whats weird is that my system test script that actually uses ADBC works just fine...

It may be related to the order NIF modules are loaded. I will take a look, it may be that some release scripts are changing the order of modules.

[DnOberon]

Thanks, I'm digging into it as well. @josevalim this is on a prod build btw
