Using strict and skipLines together causes Uncaught TypeError

[RimashMohomed]

• Operating System:Ubuntu 18.04.1 LTS (Bionic Beaver)
• Node Version:v8.10.0
• NPM Version:6.10.0
• csv-parser Version:v2.0

Expected Behavior

Given strict option is set to true and skipLines is set to 2
When skipped rows are parsed and skipped rows are validated for strict option
Then Uncaught TypeError: Cannot read property 'length' of null is return

Actual Behavior

Given strict option is set to true and skipLines is set to 2
When skipped rows are parsed
Then skipped rows should not be validated for strict option

How Do We Reproduce?

Pass in header option, {strict: true, skipLines: 2},
and use file contents:

Valuea0,Valueb0,Valuec0
Valuea1,Valueb1,Valuec1
Headera2,Headerb2,Headerc2
Valuea3,Valueb3,Valuec3
Valuea4,Valueb4,Valuec4

then result would be

Uncaught TypeError: Cannot read property 'length' of null at CsvParser._online (/home/rimash/Work/Excube/excubed/node_modules/csv-parser/index.js:202:54) at CsvParser._transform (/home/rimash/Work/Excube/excubed/node_modules/csv-parser/index.js:263:16) at CsvParser.Transform._read (_stream_transform.js:186:10) at CsvParser.Transform._write (_stream_transform.js:174:12) at doWrite (_stream_writable.js:397:12) at writeOrBuffer (_stream_writable.js:383:5) at CsvParser.Writable.write (_stream_writable.js:290:11) at ReadStream.ondata (_stream_readable.js:639:20) at addChunk (_stream_readable.js:263:12) at readableAddChunk (_stream_readable.js:250:11) at ReadStream.Readable.push (_stream_readable.js:208:10) at fs.read (fs.js:2051:12) at FSReqWrap.wrapper [as oncomplete] (fs.js:658:17)

but it should be

[{ 'Headera2': 'Valuea3', 'Headerb2': 'Valueb3', 'Headerc2': 'Valuec3' },
{ 'Headera2': 'Valuea4', 'Headerb2': 'Valueb4', 'Headerc2': 'Valuec4' }]
