Environment (please complete the following information):

  • TDengine Version 3.3.4.3
  • taos-jdbcdriver version 3.5.2

Additional Context
The problem arises in com.taosdata.jdbc.ws.tmq.entity.FetchRawBlockResp#skipSchema(),when I forcibly change withTableName to false, there won't be any problems. I did not encounter this issue when subscribing to sub tables and regular tables, as the value is false in this case
