Unable to read more than 1024 chars on ZSH + MacOS

Trying to read a long input into a variable from ZSH on MacOS.

echo "URL: "
    read URL

input is always truncated to 1024 chars... if I try and type additional chars nothing happens. - Input is copy/pasted from PostMan, its an S3 signed upload URL - If I try and delete a few chars from the end (after pasting) I am only able to manually type as many chars as I deleted - I tried using the -n option to no avail (nothing gets read into the variable) How can I read a long input? ~1500 chars
