toFormat | Adds a toFormat instance method to big.js or decimal.js | Runtime Evironment library

I'm migrating an old piece of code from Moment to Luxon and bumped into the function below:

I'm trying to write a lambda that puts a watermark on an image, then saves the result to S3. I'm using the Sharp library to do so. I'm deploying with Serverless Framework.

I'm unsure how to 'include' the image with the lambda. I'll be watermarking millions of images, so I want to avoid having to 'read' the image from S3 every time and I'd like to just have it be included in the lambda package.

For date validation, I used luxon for my app. For each function I have made unit test. My unit test passed locally but when I deployed my code in gitlab, Most of my test failed. The expected result is so different than received. I don't understand what's the wrong. This my CD/CI pipeline images. Image-1, image-2, Image-3 and there are more. Basically all my test failed

These are my all functions:

I am using luxon for my app. I have some undefined date. I validate my date with luxon's isDateTime and function returns string. I used this function multiple places of the app. Most of the places I am passing date string and only places I am getting undefined date. I manage to silent the Typescript error but I think it's not optimal solution.

I am creating few date functions for my app and for date validation I am using luxon. All of the functions, I first convert them into string then I am formatting the date. Instead of writing same line every time(to convert them into string), I have decided to create a separate function for this. When add this function my format function, I am getting typescripts error: Unsafe return of an any typed value

My table list of tours displays all the required info except that of image Cover. I cannot figure out why the image path is broken. I suspected my back-end code that serves my static files but as far as I can tell all appears to be fine.

In back-end code I have the following line of code for serving static files on my app.js file.

I am using the following code to set up a Luxon clock for my project use.

I have a datapicker class (datepicker_nfd) that is attached to an input field that uses maxdate to limit the date widget to only current dates. I have a custom knockoutjs binding to display a custom error message and reset the date when the users leaves the field (onchange). My problem is if a user manually enters a date in the future and presses enter, the widget sets the date to the current date before the onchange is fired and therefore I am unable to check to display the message. I have tried the onseect method of the datepicker and also tried to capture the "enter" keypress to no avail. Any suggestion on how to capture the manually entered date before the datepicker widget resets to current date?
