[CRASH] `dart run` fails logging `Compilation did not produce any result...` and crashes with `PathNotFoundException`

[HeySreelal]

I'm getting the following while trying to run my API built with Dart on the Ubuntu server:

root@veyilserver:~/veyilapi# dart run

Building package executable... (17.7s)
Compilation did not produce any result. Expected file at /root/veyilapi/.dart_tool/pub/bin/veyilapi/tmpCNPJMW/veyilapi.dart-3.3.4.snapshot.incremental.temp
Built veyilapi:veyilapi.
Cannot rename file to '/root/veyilapi/.dart_tool/pub/bin/veyilapi/veyilapi.dart-3.3.4.snapshot', path = '/root/veyilapi/.dart_tool/pub/bin/veyilapi/tmpCNPJMW/veyilapi.dart-3.3.4.snapshot.incremental.temp' (OS Error: No such file or directory, errno = 2)
PathNotFoundException: Cannot rename file to '/root/veyilapi/.dart_tool/pub/bin/veyilapi/veyilapi.dart-3.3.4.snapshot', path = '/root/veyilapi/.dart_tool/pub/bin/veyilapi/tmpCNPJMW/veyilapi.dart-3.3.4.snapshot.incremental.temp' (OS Error: No such file or directory, errno = 2)

Everything was functioning perfectly until I restarted the server yesterday. Now, it's completely broken. I tried uninstalling and reinstalling Dart SDK, also tried using a earlier versions (3.3.0 and 3.0.0) , couldn't get over this one.

Can somebody help with a workaround please?

I'm sorry but I'm kind of not sure if this is an issue with the language or Dart VM. Please navigate me to the right place.

Here's more info about the server and Dart versions I'm using:

Also, when I tried to run dart compile the following error occurred:

root@veyilserver:~/veyilapi# dart compile exe bin/veyilapi.dart 
Error: AOT compilation failed
Generating AOT kernel dill failed!

I'm not sure what's causing this failure, especially since I can't reproduce, but it seems like this is something we've encountered before given the comment at this line in pub.

A total shot in the dark, can you try removing .dart_tool in your project and try again? Running dart compile with --verbose might also give us some more information to work with.

@sigurdm, do you have any idea as to what could be going on here?

[HeySreelal]

I've tried discussing this issue on the Dart Community Discord server and from the suggestions, I've ran the dmesg command which contained this seemingly interesting log:

Out of memory: Killed process 1200 (dart:frontend_s) total-vm:782652kB, anon-rss:219836kB, file-rss:2304kB, shmem-rss:0kB, UID:0 pgtables:728kB oom_score_adj:0

I was running the sever on a low end machine from Digital Ocean (the $4 droplet with 512 MB memory). So, it kind of made sense.

And to your suggestion, yes, dart compile exe bin/veyilapi.dart --verbose did work for no good reason, while dart compile and dart run still failed with the same errors I've mentioned earlier.

Thanks for the suggestion :)

Oh that's interesting! Since this is an error we've encountered on our build infrastructure, there's a good chance this is related to an OOM error.

[HeySreelal]

Hope that's a lead...

The addition of the --verbose flag does the trick somehow. I'm curious why it doesn't work without this flag. If this is a OOM related error, with and without the verbose flag will have the same effect right? Or am I missing something? Thanks :)
