Question or problem
Generation of our project in the CI results in an internal failure in Tuist. If we run the generation manually on the CI agent in the same directory with the same command it succeeds. Also running generation on a developer machine does not throw the error.
Expectation
We expect the project to be generated without error.
Context
- Tuist version: 4.46.1
This is the error message:
Loading and constructing the graph
It might take a while if the cache is empty
Using cache binaries for the following targets:
Generating workspace XYZ.xcworkspace
Generating project XYZ
Resolving package dependencies using xcodebuild
