Rich text, plain text can be submitted normally, not with pictures is why?

such a rich text, ajax can submit normally if it"s just text, but why can"t I submit it if I add a picture? I ajax.error

.

500;

Mar.20,2021

does not report an error message, so it is impossible to determine specifically, but it is estimated that because the backend storage limit is exceeded, the image will be uploaded to base64 will be very large (character length)


must be that the length of the image exceeds the set limit after the image is converted to base64.


500 server error, debug with your backend, he can see the error.
