Error message

PARAM_ERROR

What it means

Thrown by saveComparisons when the batch is invalid: the first item is null, its flowId is blank, or any item in the list is null or has a different flowId. All comparison groups in one save must belong to the same workflow flowId.

Solutions

1. Ensure every WorkflowComparisonSaveReq in the list has the same non-blank flowId as the first element.
2. Fix the client so a save batch is built from a single workflow's comparison rows only.
3. Validate/sanitize the payload before sending: drop null items and check flowId equality.

Example fix

// before
List<WorkflowComparisonSaveReq> mixed = List.of(a, bFromOtherFlow);
workflowService.saveComparisons(mixed);
// after
String flowId = a.getFlowId();
List<WorkflowComparisonSaveReq> clean = reqList.stream()
    .filter(Objects::nonNull)
    .filter(r -> StringUtils.isNotBlank(r.getFlowId()) && r.getFlowId().equals(flowId))
    .collect(Collectors.toList());
workflowService.saveComparisons(clean);

Set<String> flowIds = reqList.stream()
    .filter(Objects::nonNull)
    .map(WorkflowComparisonSaveReq::getFlowId)
    .filter(StringUtils::isNotBlank)
    .collect(Collectors.toSet());
if (flowIds.size() != 1) throw new BusinessException(ResponseEnum.PARAM_ERROR);

boolean singleFlow = list != null && !list.isEmpty() && list.stream().allMatch(r -> r != null
    && StringUtils.isNotBlank(r.getFlowId())
    && r.getFlowId().equals(list.get(0).getFlowId()));

try {
    workflowService.saveComparisons(reqList);
} catch (BusinessException e) {
    if ("PARAM_ERROR".equals(e.getCode())) {
        // rebuild the batch from a single workflow's rows
    } else { throw e; }
}

When it happens

Trigger: Submitting a comparison batch where entries carry inconsistent flowIds (e.g. merging rows from two workflows), passing null elements in the JSON array, or omitting flowId on the first item.

Common situations: Client-side state mixing rows from a previous edit session; copy-paste of comparison rows between workflows; malformed request payload where flowId is missing on some items.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
