Description

I found a bug in the canal code. 'canal-json.table.include' does not filter out the binlog of the specified table correctly, which will cause an error in the parsing section. For example, if I want to read the binlog of canal-json.table.include = 'a' table, there is a source field of int in table a, but at this time if table b also has a source field of string, An error will be reported.
