ext_emconf.php: invalid dependency with a composer installation
I've installed gkh_rss_import through composer, and I've got this error:
#1439552058: The extension "gkh_rss_import" has invalid version constraints in depends section. Extension key is missing!
It seems to be related to an issue with the TER (#75979).
Apparently, you have to resubmit the extension on the TER in order to fix it.
Could you do that?
