get an Uknown error when trying to executing a long query in NodeJs using mssql module

Question

When i try to execute a long query using NodeJs [email protected] for some reason i get an unknown error, not sure if it is because the query uses a UNION to join result from other similar table with the same column names or what. When i use the same sqlHelper.js code to run other short queries from the same tables and it works fine, like for example executing something line this:

Select * from tblMenuVerticalLevel0

All the tables have the same schema, and i have added the schema below. Also i want to note that when i run the same query using SQL Studio it works fine, noy sure why nodejs won't even execute, i place a break point in visual studio the line after the query has been added to memory to the sqlQuery variable, then copied and pasted it into sql studio ran it and it returns the result not sure why nodejs mssql module won't execute it, anyone has any idea why this is happening?
