I have some table fields in NumberDecimal format. When I am going to fetch data through query it gives an error.  
TypeError: Cannot read property ‘type’ of undefined

Did you insert this data using Parse?

No, We have an existing database and we are now shifting to Parse.

I’m not sure that Parse Server will be able to handle this existing type of data since it does not implement any field type that converts to Decimal128. You will probably have to transform it to another “Parse field type”.
