I believe that this is not due to going to 2019a, but related to recent permission lockdowns on /tmp directory (linux). I need to figure out how to point matlab to a different temp directory to test this.
Why did imread() stop working when I changed to 2019a?

I have been using imread to get images from a server by putting requests into the URL argument: im = imread(url). Now I'm getting an error "Can't read URL, ..., Reason: first input must be 1xN cell array of strings." What is it talking about?
EDIT: I wasted everyone's time with this. After digging deeper, I found that I had an old version of strjoin() in my path somehow. The function must have changed in a critical way. Problem disappeared when I removed this old version.

Can you show us the class and size of the url variable you're passing into imread?
Is it a character vector or a string scalar as the documentation page for the imread function indicates it needs to be? See the section describing the Input Arguments, specifically the filename input argument.

It looks like that would not give a simple filename, but possibly a list of a whole bunch of filenames. I suggest you somehow use webread() to execute that query and then parse out the filenames one at a time.
