Couldn't find Git Commit or Branch with name main

[LordLyng]

I'm unsure what I'm doing wrong here.

I more or less copied the example from the For building PRs section of the README. the only exception is that I use v4 of the checkout action and v4 of the setup dotnet action.

When I run the dotnet-affected action i get the following error: Unhandled exception: System.InvalidOperationException: Couldn't find Git Commit or Branch with name main in repository /home/runner/work/itm_sursen4-backend/itm_sursen4-backend/.git/ at DotnetAffected.Core.GitChangesProvider.GetCommitOrThrow(Repository repo, String name) in /_/src/DotnetAffected.Core/GitChangesProvider.cs:line 152 at DotnetAffected.Core.GitChangesProvider.GetCommitOrHead(Repository repository, String name) in /_/src/DotnetAffected.Core/GitChangesProvider.cs:line [13](https://github.com/it-minds/itm_sursen4-backend/actions/runs/11343124706/job/31545025965#step:5:14)5 at DotnetAffected.Core.GitChangesProvider.ParseRevisionRanges(Repository repository, String from, String to) in /_/src/DotnetAffected.Core/GitChangesProvider.cs:line 82 at DotnetAffected.Core.GitChangesProvider.GetChangesForRange[T](Repository repository, String from, String to) in /_/src/DotnetAffected.Core/GitChangesProvider.cs:line 101 at DotnetAffected.Core.GitChangesProvider.GetChangedFiles(String directory, String from, String to) in /_/src/DotnetAffected.Core/GitChangesProvider.cs:line 24 at DotnetAffected.Core.Processor.AffectedProcessorBase.DiscoverChangedFiles(AffectedProcessorContext context) in /_/src/DotnetAffected.Core/Processor/AffectedProcessorBase.cs:line 57 at DotnetAffected.Core.Processor.AffectedProcessorBase.Process(AffectedProcessorContext context) in /_/src/DotnetAffected.Core/Processor/AffectedProcessorBase.cs:line 22 at DotnetAffected.Core.AffectedExecutor.Execute() in /_/src/DotnetAffected.Core/AffectedExecutor.cs:line 41 at Affected.Cli.Commands.InvocationContextExtensions.ExecuteAffectedExecutor(InvocationContext ctx) in /_/src/dotnet-affected/Commands/Binding/InvocationContextExtensions.cs:line 38 at Affected.Cli.Commands.AffectedRootCommand.<>c.<<-ctor>b__4_0>d.MoveNext() in /_/src/dotnet-affected/Commands/AffectedRootCommand.cs:line 38 --- End of stack trace from previous location --- at System.CommandLine.Invocation.AnonymousCommandHandler.InvokeAsync(InvocationContext context) at System.CommandLine.Invocation.InvocationPipeline.<>c__DisplayClass4_0.<<BuildInvocationChain>b__0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c__DisplayClass17_0.<<UseParseErrorReporting>b__0>d.MoveNext() --- End of stack trace from previous location --- at Affected.Cli.ErrorHandlingMiddleware.<>c__DisplayClass0_0.<<UseRenderingErrorHandler>b__0>d.MoveNext() in /_/src/dotnet-affected/CommandLine/ErrorHandlingMiddleware.cs:line 26 --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c__DisplayClass12_0.<<UseHelp>b__0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c__DisplayClass22_0.<<UseVersionOption>b__0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c__DisplayClass19_0.<<UseTypoCorrections>b__0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c.<<UseSuggestDirective>b__18_0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c__DisplayClass[16](https://github.com/it-minds/itm_sursen4-backend/actions/runs/11343124706/job/31545025965#step:5:17)_0.<<UseParseDirective>b__0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c.<<RegisterWithDotnetSuggest>b__5_0>d.MoveNext() --- End of stack trace from previous location --- at System.CommandLine.Builder.CommandLineBuilderExtensions.<>c__DisplayClass8_0.<<UseExceptionHandler>b__0>d.MoveNext()

I tried copying the command executed during my workflow and ran it lcoally with no issues.

worth noting i get an error when testing this in a PR. The command executed by the actions is /usr/share/dotnet/dotnet affected -f text traversal --from custom/workflow-dispatcher --to main

[LordLyng]

I did some more research and found out that if i prefix both the to and from with origin/ it seems to work.

So the problem most likely comes from either checkout not checking out the base and head ref as heads during pr checkout, or the way LibGit2Sharp handles populating remote urls.

working workflow example, not sure if it's ideal though

hi @LordLyng ,I think we may need to review the example you've linked in order to make it work properly. Not sure if something changed in the tool that caused the breaking change, or if it is something else that changed. Leo.
