Trying to query data where string has a single quote - procedure

Question

Trying to go through a list of values where there might be one with a single quote in it. When I try to pass it through a function, it fails.
It gives the error,
Execution error in store procedure REPORT_PRESENTATION_DATA: SQL compilation error: parse error line 1 at position 164 near '<EOF>'. syntax error line 1 at position 158 unexpected 't'. At Statement.execute, line 90 position 41
I then add
myCommonValue = myCommonValue.replace("'","''");
but now get the error,
JavaScript execution error: Uncaught TypeError: Cannot read property 'replace' of null in REPORT_PRESENTATION_DATA at ' myCommonValue = myCommonValue.replace("'","''");' position 36 stackstrace: REPORT_PRESENTATION_DATA line: 85
Here's a code sample:
CREATE OR REPLACE PROCEDURE MY_SNOWFLAKE_PROCEDURE()
RETURNS VARIANT
LANGUAGE JAVASCRIPT
AS
$$
...
sqlText = ` SELECT fields FROM MYTABLE `;
statement = snowflake.createStatement({ sqlText });
const rs = statement.execute();
let results = [];
while (rs.next()) {
let myColumnValue = rs.getColumnValue(1);
myColumnValue = myColumnValue.replace("'","''");
// Using the column value which could contain a single quote in the string,
// get a second result set. IE: "gov't" may be the string value passed into Query_GroupValues
sqlText = ` SELECT * FROM table(Query_GroupValues('${startdate}', '${enddate}', ARRAY_CONSTRUCT('${myColumnValue}'))) `;
statement = snowflake.createStatement({ sqlText });
const rsTableValue = statement.execute();
if (statement.getRowCount() > 0) {
let myValue = rsTableValue.getColumnValue(1);
struct = {
attributes: {
value: myValue
}
}
results.push(struct);
}
}
...
$$;

Looks like myColumnValue was null when it's replace() method was invoked. Adding a guard should fix it. For Example: if (myColumnValue!=null) myColumnValue = myColumnValue.replace("'","''");
