problem description

there are two types of logs in a stream, one containing classNo fields and the other containing classNO fields (yes, the only difference is case, but I can"t change it yet! The contents of the two fields are actually the same, but the other fields of the two logs are not exactly the same.
for example: a log content is {"name": "a", "classNo": "aaa-111-001"}, B log content is {" name ":" b "," age ":" 12 "," classNO ":" bbb-111-002"}, C log content is {"name": "cc", "classNo": "cc-111-001"," marjor ":" english "}

the platform version of the problem and what methods you have tried

after adding a rule such as classNo regular match to the rules of stream, there is only a log with a classNo field in stream, and another kind of log is missing. Conversely, it is the same with using classNO as the Filter rule.
