Hi!
Is it works with other type (not webp)? Where from values of source_fname, size, dest_fname comes? It is not clear.
But mainly, you have to set Content-Type header and print image to request response body. When you call ngx.exec file with image thumb is not saved to disk yet. My guess.

hi,
thanks for your answer. yes. it works with jpg format. so it cant be that is something from with source_fname, size, dest_fname . also the mime.type is set correctly through nginx
root@6d7ba1f427a4:/# grep webp /usr/local/openresty/nginx/conf/mime.types image/webp webp;
its really strange. it seems that webp isnt supported from magick with luarocks maybe?
For webp you need not only libgraphicsmagick1 but libwebp-dev also: RUN apt-get update -y && apt-get install -y git autoconf libtool-bin libmagickwand-dev webp libwebp-dev && rm -rf /var/lib/apt/lists/*
hi @alexandrim0
great! that worked like a charm. muchas gracias!
Thanks for your time!
