This is really strange that the patches are coming through as empty for you. Sorry about that! Just to be sure that we understood correctly do you mean your email client actually doesn’t display the patches? because we can see them in the email you replied to.
I followed this
documentation to send the patches and it worked fine for previous patches. We have also pushed the patches to the yocto metrics
contributors branch in case you can't view the email patches.
Please let me know if there is any other way to share the patches or if I should rensend the patches. Thanks so much!
