`The command "dotnet paket restore" excited with code -532462766` on a fresh SAFE template

[Freymaurer]

Hey guys, i never encountered this error before, but we wanted to setup a SAFE project for a new colleague and we got an error The command "dotnet paket restore" excited with code -532462766. We tested this also for a fresh SAFE stack and still the issue persists. I have no idea why this issue happens. We "solved" it by removing paket and using simple dotnet dependencies but this is obviously no real solution.

This is not my machine, but i will try to answer asap if you want more information on this. But i do not expect you to solve this obscure issue. Just wanted to let you know.

We also tried running dotnet watch run src/Server/Server.fsproj without fake with the same result and tried building the projects which worked just fine.

The machine uses:

• Win 11
• .net8.0, node 20 and npm 9

I've definitely seen this error code before. Last time it was to do with missing paket.references from the Shared directory causing Paket to use the wrong version of FSharp - this is now fixed as of 8 months ago.

Maybe these will help diagnose the issue:

• What version of the SAFE template is being used?
• What is the output of dotnet --list-sdks?
• What is the output of dotnet build -v:d? (from the src/Server directory)

[Freymaurer]

Hello! Thanks for the quick response!

What version of the SAFE template is being used?

The newest version v5.0.6

What is the output of dotnet --list-sdks?

What is the output of dotnet build -v:d? (from the src/Server directory)

Duplicate of #612, thanks for your report @Freymaurer! the other issue has a workaround in the discussion

@baronfel ok. I've found some more information on this.

TLDR: If you dotnet watch build from the folder of the project, and you're using Paket, and a version of .NET 8 post 8.0.206, things go wrong. If you dotnet watch build from outside of the folder of the fsproj e.g. dotnet watch build src/server, then it works.

I suspect it's something that's changed since 8.0.206 that has somehow broken Paket. Here are some steps to reproduce:

1. Install a version of .NET after 8.0.206 (I'm using 8.0.304).
2. dotnet new SAFE (I'm using 5.0.7).
3. dotnet watch build src/server - works ✅
4. cd src/server
5. dotnet watch build - pops ❌
6. dotnet build - works ✅
7. Change global.json to pin to 8.0.206.
8. dotnet watch build - works ✅
9. Revert change to global.json.
10. Clear out everything in Server.fs to just e.g

module Server
[<EntryPoint>]
let main _ = 0

11. In Server.fsproj, remove the reference to Shared and the Import of Paket.Restore.targets.
12. dotnet watch build - works ✅

I don't always get a stack trace but when I do, it's this:

Also tagging @forki as it could relate to Paket.

Update 1

I've just observed that the "workaround" of calling it from a different folder does not work for dotnet watch run. It only works for dotnet watch build.

Hello there - just went to update my Mortgage app and hit exactly this! Great timing haha

[Ryan-Palmer]

FYI my temp workaround was to just add --no-restore to the dotnet watch run command

[isaacabraham]

ooooh that's interesting

[isaacabraham]

I was even thinking to add that to the template anyway because it's rarely needed anyway as part of watch run.

experiencing the same error on mac os/x

.paket/Paket.Restore.targets(171,3): error MSB3073: The command "dotnet paket restore" exited with code 134. [src/Shared/Shared.fsproj]

and the @isaacabraham workaround above of pinning the .net sdk in global.json to 8.0.204 works.

I've rerun the failing test thread above and both .NET SDK 8.0.400 and 9.0.100-rc.1 work like a charm - I'd highly suggest moving to those feature bands. As it is, this is a regression only on the 8.0.3xx branch from what I can see.
