Failed to find validation configuration from given test…

Error message

Failed to find validation configuration from given test case data path.

What it means

The component validation runner derives a validation configuration from a test-case data path; if the path does not exist or contains no recognizable test-case layout, `get_validation_configuration_from_test_case_path` returns None and the code panics with this message. It is a CLI-user-facing panic for the `vector validate` component-testing feature.

Solutions

1. Verify the test-case data path exists: `ls <path>` from the working directory where you invoke vector
2. Pass the directory containing the validation test-case data (with its expected test case files), not a bare config file
3. Use an absolute path to rule out working-directory issues
4. Run `vector validate --help` to confirm the expected input layout

Example fix

// before
vector validate ./component-tests/smoketest
// after (path corrected to existing test case dir)
vector validate ./tests/component_validation/smoketest

// before invoking vector validate
test -d "$TEST_CASE_PATH" && echo ok || echo "missing test case path: $TEST_CASE_PATH"

When it happens

Trigger: Running `vector validate <path>` (component validation) with a path that doesn't exist, isn't a directory, or doesn't contain the expected test-case file layout.

Common situations: Typo in the test-case directory path; passing a single component config file instead of a validation test-case data directory; running validation from a different working directory with a relative path.
