validator.js | Laravel styled JavaScript Object/Form/JSON validation | Validation library

I am working to validate data input from an API call using express-validator version 6.11.1 and every time I validate using either check or body, I get the error below:

TypeError: body(...).not(...).IsEmpty is not a function

I created a helper called validator.js with the code below

i'm relatively new to coding. So I'm sorry if there are already 100 posts from this.

My problem is the following: I want to simply query my DynamoDb using Lambda and Api Gateway.

Unfortunately I get the following error message:

i have project that takes alot of validations using Express-Validator , so each time i need to validate something , i do like that in each file:

My code consist of route, global error handler and one validation function. First version of the code was totally synchronous and everything worked fine. Now I am trying to make it asyc so the validation function looks like this:

I am fairly new to react. I have an ask that requires email validation and I found an npm package called validator.js that handles that. So I built a custom Gutenberg WordPress block with email addresses included. The code I have to call in validator seems to make the block stop rendering. Here is the code:

I've made a form and a validation function that goes with it. I enqueued the javascript in the function.php and it gets loaded. The only page that I want this .js to be run on is reservation.php so I've added if ( is_page_template( 'reservation.php ) ). I have also enqueued some jquery that way which also gets loaded but that actually works.

The problem is that none of my .js functions are working.

For example amongst them I have an onblur function which does not trigger.

If I look at the Network tab in F12 tools, I can see that the formValidator.js was loaded, and it has status 200.

Any help would be welcome. If I can provide any additional information, feel free to ask.

Thank you.

Code executes perfect on local system but when I upload it to lambda functions then it gives error:
