DB input stopped after changing rising column field type from int to bigint (DB connect v1.1.7 & MySQL)

Hi, the DB input was working well until I change rising column field type from int to bigint.

We found the following error message.

Find this error message:

2018-12-10 11:18:59.363 dbx2296:ERROR:TailDatabaseMonitor - DBMon Error while executing monitor=[dbmon-tail://host/table1]: com.splunk.dbx.monitor.DbmonException: Value of rising.column=status_id cannot be stored (not serializable)

state.xml for this db input:

<list>
<value key="latest.id">
<value class="int">611538309</value>
</value>
</list>

What did I missed?

You are aware that DBX 1.x reached End of Life in like 2016, correct?

The root cause is class type changed so db input can't parse correctly.
Change state.xml as following works

<list>
 <value key="latest.id">
 <value class="big-decimal">611538309</value>
 </value>
 </list>
