HTML/JS Kanban Board doesn't let me drop newly created tasks into other columns

I am creating a Kanban Board in HTML/JS/CSS and am close to finishing my MVP here. Everything is working as expected, except for one thing. When I create a new task, I am able to drag it (seemingly) but not DROP it into any other columns. The sample tasks I have do not have this problem and I am ripping my hair out trying to figure out what the issue is. When I attempt to drag and drop newly created tasks into other columns, I get this error:

TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.
    at drop (/script.js:31:13)
    at HTMLDivElement.ondrop (/:45:112)

I am using basic drag and drop API stuff for HTML and JS and literally only need to make this work in order to finish my MVP. Any help is appreciated. NOTE: The line numbers in the above error change based on what column I try to drop the new task into but the error itself stays the same.

Here is my code:

index.html:

    <meta charset="utf-8">

Again, if anyone knows what my issue is here, the help is greatly appreciated. Thanks!
