Hi, according to the public review's documentation an image size needs to be between 50 x 50 and 10000 x 10000 pixels. PDF pages must be 17 x 17 inches or smaller and the file size of the image must be less than 20 megabytes (MB).

I have a file that satisfies all requirements yet still faces this error:

"error": {

    "code": "InvalidImageSize",

    "message": "The input image is too large. It should not be larger than 20MB."

}

I try creating another file with the same resolution but with fewer texts. This time it works. Could you please have a look ?
