Error message

不支持的延迟类型：{}

What it means

While converting a BPM simple-model DELAY_TIMER_NODE to Flowable BPMN, SimpleModelUtils throws UnsupportedOperationException when delaySetting.delayType is neither FIXED_DATE_TIME (delay until an absolute time) nor FIXED_TIME_TIME_DURATION — here FIXED_TIME_DURATION (delay by a duration). The two supported types map to a Timer Boundary Event with a timeDate vs timeDuration expression; any other value has no BPMN representation in this converter.

Solutions

1. Set delayType to 1 (FIXED_DATE_TIME) or 2 (FIXED_TIME_DURATION) on the delay node in the designer
2. Upgrade the BPM server module to the version whose enum covers the delay type the designer emits
3. Ensure the frontend always sends a delayType whenever a delaySetting object is attached

Example fix

// before (process JSON node)
{"type":"DELAY_TIMER_NODE","delaySetting":{"delayType":null,"delayTime":"PT10M"}}

// after
{"type":"DELAY_TIMER_NODE","delaySetting":{"delayType":2,"delayTime":"PT10M"}} // 2 = FIXED_TIME_DURATION

Integer t = node.getDelaySetting() != null ? node.getDelaySetting().getDelayType() : null;
if (t == null || !(t.equals(BpmDelayTimerTypeEnum.FIXED_DATE_TIME.getType())
        || t.equals(BpmDelayTimerTypeEnum.FIXED_TIME_DURATION.getType()))) {
    throw new IllegalArgumentException("delayType 必须为 1(固定时间点) 或 2(固定时长)");
}

boolean isValidDelayType(Integer delayType) {
    return delayType != null && Arrays.stream(BpmDelayTimerTypeEnum.values())
        .anyMatch(e -> e.getType().equals(delayType));
}

When it happens

Trigger: A delay timer node in the simple designer whose delayType is null or an out-of-range integer (e.g. 3+); process JSON imported from a version whose BpmDelayTimerTypeEnum defines more types than the deployed server supports; delaySetting present but delayType left unset by the frontend.

Common situations: Frontend designer newer than backend server (extra delay types); manually crafted simple-model JSON; partial save leaving delayType null while delaySetting object exists.
