Error: Failed to find kernel binary in cargo metadata output

I was following the OS tutorial, and ran into an issue when using cargo bootimage.

→ cargo bootimage --target ./x64_86-darkos.json

Error: Failed to find kernel binary in cargo metadata output

When looking through to target folder, it did spit out a file that looks to be the kernel binary:

Not exactly sure how to solve this issue.

My os is Windows (11) and my cargo version is cargo 1.77.0-nightly (1ae631085 2024-01-17)

Reproduce cargo bootimage --target ./x64_86-darkos.json on Windows 11 and compare the cargo metadata output with the binary produced in the target folder. Start with the bootimage handling of cargo metadata and the x64_86-darkos.json target; done means the generated kernel binary is correctly identified instead of reporting that it is missing.
