Hey @cihakmar, thanks for opening the issue. I've create this app to reproduce the issue https://github.com/OS-pedrogustavobilro/capacitor-plugins-issue2460-share, I've reproduced it on iOS trying to share a vcard to Gmail, and I get that error "The files that you are trying to attach are invalid". I'm not getting an equivalent error when sharing the the apple Mail app, so there should be some difference in how some applications receive certain files.

I'm not sure yet if this is something that can be fixed in the plugin, a deeper investigation is required.
