Why I got error 102 in makefile when running nextest.

[BraveY]

This action works successfully on Wed, 12 Mar 2025 03:14:50 GMT.
But it failed on 13 Mar, in this aciton workflow, I got following error:

TEST_WORKDIR_PREFIX="/tmp" RUST_BACKTRACE=1 /home/runner/.cargo/bin/cargo nextest run --no-fail-fast --filter-expr 'test(test) - test(integration)' --workspace  --features=virtiofs --release --test-threads 8
make: *** [Makefile:[11](https://github.com/dragonflyoss/nydus/actions/runs/13826281977/job/38681749367#step:6:12)1: ut-nextest] Error 102
Error: Process completed with exit code 2.

I am wondering why I got Error 102? Is there any updates on 13 Mar caused the error? Since there is no update in our program between 12 Mar and 13 Mar.

This docs say Error 102 is Running cargo metadata produced an error. But it is ok, when i add command cargo metadata in smoke test.

And when i run the test command TEST_WORKDIR_PREFIX="/tmp" RUST_BACKTRACE=1 /home/runner/.cargo/bin/cargo nextest run --no-fail-fast --filter-expr 'test(test) - test(integration)' --workspace --features=virtiofs --release --test-threads 8 in smoke directly, i got the output as expected.

The makefile is here. And the related part is fllowing:

# you need install cargo nextest first from: https://nexte.st/book/pre-built-binaries.html
ut-nextest: .release_version
	TEST_WORKDIR_PREFIX=$(TEST_WORKDIR_PREFIX) RUST_BACKTRACE=1 ${CARGO} nextest run --no-fail-fast --filter-expr 'test(test) - test(integration)' --workspace $(EXCLUDE_PACKAGES) $(CARGO_COMMON) $(CARGO_BUILD_FLAGS) --test-threads 8
