Error Message trying to upload an image.

I tried creating a post with an image in it. I got the following error message displayed in my browser:

{"data":{"files":null,"msg":"Too wide"},"state":"success"}

Is there something wrong with my image? I was trying to reupload this one from reddit: https://preview.redd.it/2jxm187wf4a81.png?width=11320&format=png&auto=webp&s=494d575dd3110b67b37b1c67afa9e713fd258a07

Should I try again after resizing?
