WebP Express validation error

All widths are specified in attr srcset, but W3C Validation throws error
Error:

Bad value data:image/svg+xml;charset=utf-8,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%271280%27%20height%3D%27720%27%20viewBox%3D%270%200%20194%2069%27%2F%3E for attribute srcset on element img: No width specified for image data:image/svg+xml;charse…0%200%20194%2069%27%2F%3E. (When the sizes attribute is present, all image candidate strings must specify a width.)

Code:

Is it because of the symbols in pic’s path? Is there any way to fix it in the settings, or do i have to alter plugin’s code now?
