Solutions

1. Inspect the logged underlying exception (stack trace in server logs) for the real cause
2. Verify database connectivity and that the experiment/evaluator mapping tables exist
3. Validate the request's pageNum/pageSize values before querying
4. Catch the RuntimeException in the controller and map it to a 500 with the cause id

Example fix

// before
} catch (Exception e) {
    throw new RuntimeException("查询评估器关联的实验失败: " + e.getMessage());
}
// after
} catch (DataAccessException e) {
    log.error("查询评估器关联的实验失败: {}", request, e);
    throw new StudioException(StudioException.INTERNAL_ERROR, "查询评估器关联的实验失败");
}

if (request.getPageNum() == null || request.getPageNum() < 1 || request.getPageSize() == null || request.getPageSize() < 1) { throw new IllegalArgumentException("invalid paging"); }

null

try { service.getExperimentsByEvaluator(request); } catch (RuntimeException e) { log.error("evaluator experiment query failed", e); return ResponseEntity.internalServerError().body("query failed: check server logs"); }

When it happens

Trigger: Any database error during the evaluator-experiment page query (table missing, bad SQL, connection failure) or an unexpected runtime error (e.g. NPE) inside the try block.

Common situations: Database down or unreachable from the admin server; schema drift after upgrade; malformed page request (pageSize/pageNum out of expected range) causing query failure.

Understand the failure class

Background: Database query failed: Internal Server Error 500s wrapping SQL, Prisma, and connection failures — what to check first — this error's family across 16 libraries.
