Error message

TPC10050001

What it means

TPC10050001 signals that a TPC MQ message cannot be persisted because its messageTopic is empty. saveMessageWaitingConfirm validates topic presence before mapping the DTO and creating a WAIT_SEND message record.

Solutions

1. Set messageTopic on the TpcMqMessageDto before calling saveMessageWaitingConfirm.
2. Validate the topic at the producer's construction point to fail fast.
3. Check that the field name/copy mechanism (mapper, beanutils) actually populates messageTopic.

Example fix

// before
TpcMqMessageDto dto = new TpcMqMessageDto();
dto.setMessageBody(body);
tpcMqMessageService.saveMessageWaitingConfirm(dto);
// after
TpcMqMessageDto dto = new TpcMqMessageDto();
dto.setMessageTopic("user-topic");
dto.setMessageBody(body);
tpcMqMessageService.saveMessageWaitingConfirm(dto);

if (dto == null || StringUtils.isEmpty(dto.getMessageTopic())) {
    throw new IllegalArgumentException("messageTopic is required");
}

try {
    tpcMqMessageService.saveMessageWaitingConfirm(dto);
} catch (TpcBizException e) {
    if ("TPC10050001".equals(e.getMessage())) { /* surface 'topic required' to caller */ }
    throw e;
}

When it happens

Trigger: Calling TpcMqMessageServiceImpl.saveMessageWaitingConfirm with a TpcMqMessageDto whose messageTopic is null or an empty string.

Common situations: Producer code forgets to set the topic before building the DTO; topic field lost when copying from a config object or map; refactored DTO construction dropped setmessageTopic.
