Assertion Error

### Version
Please specify the versions you are using. Exact version numbers are preferred.
- Pymyrepl (e.g., 1.0.2):
- OS (e.g., Ubuntu 18.04):
- Database and version (Remove unnecessary options):
- MySQL: 10.23
- MariaDB: 5.3
- `binlog_row_metadata`: None

### Symptoms
I have a prod db, where somw insert queries are running on top of it, I am trying to replicate in snowflake. But while reading the insert event, while getting binlog_event.event.rows throwing

Assertion Error
Expected = 111. Actual = 46. Position=130. Data=176

And I am getting the assertion error for column type varchar,

### Steps to Reproduce
I cannot help you in reproducing as I am testing in prod environment

I tried with many version degrading and upgrading with all the modules such as pymysql, mysql-replication, s3, etc..

The report points to binlog_event.event.rows and a varchar assertion with expected 111 versus actual 46 at position 130, but names no source file or test. Start by locating the row-event parsing entry point and inspect how the column metadata is interpreted; done means reproducing the assertion with a representative binlog event and identifying a verified fix or a precise missing reproduction detail.
