Logging a procedure information into a table in snowflake - snowflake-cloud-data-platform

Question

I have a table that logs certain information about procedures that are called
PROCEDURE_NAME, PARAMETERS_PASSED, START_TIME,END_TIME, ERROR_MESSAGE ... and others
I am creating a procedure which inserts into this table the information I want.
However, I do not know how I am to pass the error message from the stored procedure that is called
into my new procedure
Is there a way to save this error message
EX)
SP1 - STARTS
SP1 - ENDS & THERE IS AN ERROR
LOG_STORED_PROCEDURE(SP1_NAME,SP1_PARAMETERS,SP1_START_TIME,SP1_END_TIME,ERROR_MESSAGE)

Use JavaScript's try/catch block and do the insert into an error table in the catch block. Here's a sample you can modify:
create or replace procedure catch_error_example()
returns string
language javascript
execute as caller
as
$$
// Try to insert into a non-existent table.
try{
cmd = {sqlText: "insert into NON_EXISTENT_TABLE select 1"};
stmt = snowflake.createStatement(cmd);
stmt.execute();
} catch (e) {
cmd = {sqlText: `insert into ERROR_LOG (STORED_PROC, ERROR_MESSAGE) values ('CATCH_ERROR_EXAMPLE', '${escapeString(e.message)}')`};
stmt = snowflake.createStatement(cmd);
stmt.execute();
}
return "Check error log.";
function escapeString(value) {
var s = value.replace(/\\/g, "\\\\");
s = s.replace(/'/g, "''" );
s = s.replace(/"/g, '\\"');
s = s.replace(/\s+/g, " ");
return s;
}
$$;
create temp table ERROR_LOG(ERROR_TIME timestamp default current_timestamp, STORED_PROC string, ERROR_MESSAGE string);
call catch_error_example();
select * from ERROR_LOG;
