413 request entity too large

I am using aspose imaging to convert my layered tiff image to psd but the api call returns the following response:

Error: 413 b'<html>\r\n<head><title>413 Request Entity Too Large</title></head>\r\n<body>\r\n<center><h1>413 Request Entity Too Large</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n'

Even though my input file is just 10 MBs in size.
Any solutions for this?

Hello,
the issue is fixed, please, try again

Best Regards,
Alexander
