mysql query does not see null values in nodejs

Question

I consume messages from Rabbitmq and trying to write to mysql. I read messages like this

Object.values(JSON.parse(msg.content.toString()))

I console.log the consumed message as shown below;

[
  null,
  '2016-03-06T22:00:00.000Z',
  null,
  null,
  796,
  null,
  'Weekday',
  null,
  null,
  null,
  null,
  null,
  'fff2d9b2-2db9-4fea-96e9-7a4ce5cdda7f',
  '2022-09-08T10:42:43.876Z',
  '2022-09-08T13:43:06.000Z',
  'fc0cca6947244bfb546a409a5512d8bd'
]

But when write it into mysql, it writes like this insert into date_d (day,date,year,month,date_id,quarter,weekend,day_of_week,day_of_year,day_of_month,week_of_year,month_of_year) values (,2015-09-27T21:00:00.000Z,,,635,,Weekday,,,,,,1bbbfb7a-64cc-46a8-bdc8-a

insert script shown below

"insert into date_d (" + res  + ") values (" + Object.values(JSON.parse(msg.content.toString())) + " )" 

But mysql deletes null values than it gives me below error.

"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ',2015-09-27T21:00:00.000Z,,,635,,Weekday,,,,,,1bbbfb7a-64cc-46a8-bdc8-a7b7a02b3e' at line 1",

Any help please thanks.
