Invalid experiment status: {}

Error message

Invalid experiment status: {}

What it means

ExperimentServiceImpl.list logs this warning when the request's status string cannot be converted to an ExperimentStatus via ExperimentStatus.fromCode. Instead of failing the request, the code catches the IllegalArgumentException, logs the invalid value, and continues the query with status == null (i.e., the status filter is silently ignored), which can return more rows than the caller expected.

Solutions

1. Validate the status string against ExperimentStatus codes on the client/server before calling list().
2. Trim and normalize (uppercase) the status string before mapping.
3. Fix the caller to send the exact code returned by ExperimentStatus.getCode().
4. If you need a hard failure instead of silent filtering, throw in the catch block rather than logging.

Example fix

// before
request.setStatus("Completed"); // ignored: not a valid code

// after
String code = ExperimentStatus.COMPLETED.getCode();
request.setStatus(code); // or validate: ExperimentStatus.fromCode(raw.trim().toUpperCase())

public static void validateStatus(String raw) {
    if (StringUtils.hasText(raw)) {
        ExperimentStatus.fromCode(raw.trim()); // throws IllegalArgumentException if invalid
    }
}

try {
    results = experimentService.list(request);
} catch (IllegalArgumentException e) {
    // reject the request instead of silently ignoring the filter
    throw new ResponseStatusException(HttpStatus.BAD_REQUEST, "Invalid experiment status");
}

When it happens

Trigger: Calling experimentService.list(request) with request.setStatus("RUNNIG") or any string that is not a valid ExperimentStatus code (e.g., free-text like "running " with whitespace, wrong case, or an old enum code removed in an upgrade).

Common situations: Frontend sends a human-readable status label instead of the enum code; API version change renamed status codes; user typo in a query param; locale-specific status strings.

Understand the failure class

Background: Invalid enum value errors: "Unknown type", "Invalid scope", "must be one of" — when a string is not on the library's allowed list — this error's family across 23 libraries.
