I have been trying to post an image of my cat for a few days now, and consistently get this error, or one that just says "no value for error." Is this a problem with Jerboa, or with my instance, vlemmy?
That means that the image you're trying to post is over 100kb. I suggest you converting your image to the webp format in an online converter and compressing it later. If that doesn't work, you're screwed
The limit can be changed, but it's up to the admins of the instance.
It also might be nice to change the error so that users know to shrink their images.
Its not strictly a Lemmy error, but in Nginx (or at least for me it was there), which is a service that sits between you and Lemmy and redirects traffic. But yeah, the frontend could still handle it better and at least give a better error message
