Datatable entry manipulation

I have entry saved in Datatable and entry contains an infotable in it and i have two entries in it and i want to delete one of the version data from it which is on index 1. I have attached the screenshot also.

I have written a code which is removing the infotable value which is on index 1 but i am unable to update the datatable. Can someone please see whats a mistake here.

let entry = Things["TestBench_Entries_SCW1.DT"].GetDataTableEntryByKey({key:"1709798512000SCW1E-SCW-SEM-01"});
logger.info("1"+entry.rows);

 let values;
if ( entry.rows[0].versionData && entry.rows[0].versionData.rows && entry.rows[0].versionData.rows.length > 1 ) {
 


 
 
 //logger.info("2" + entry.rows[0].versionData.RemoveRow(1));
 
 values = Things["TestBench_Entries_SCW1.DT"].CreateValues();
 values.entryTimeStamp = entry.rows[0].entryTimeStamp; // STRING [Primary Key]
 values.Location 		 = entry.rows[0].Location; // INFOTABLE
 values.Position = entry.rows[0].Position; // DATETIME
 values.entryDate = entry.rows[0].entryDate; // STRING
 values.status = entry.rows[0].status;// STRING
 values.tinNumber = entry.rows[0].tinNumber;// STRING
 values.versionData = entry.rows[0].versionData.RemoveRow(1);// STRING
 
}


logger.info("Jamal" +entry.rows[0].versionData.rows.length);

Things["TestBench_Entries_SCW1.DT"].AddOrUpdateDataTableEntry({values:values});
result = entry;

now funny thing is i have just set a logger to remove it and in result it shows me the infotable with removed that entry but here in this code i get null ==> entry.rows[0].versionData.RemoveRow(1)
