The link you sent is a fix for the problem discussed here: https://github.com/obspy/obspy/issues/1872
But it doesn’t seem to fix the problem discussed here: https://github.com/obspy/obspy/issues/2090
which is related to the presence of the ">” symbol in the SC3 filter grammar.
Could you please comment on the GitHub issue page: https://github.com/obspy/obspy/issues/2090
and/or on the pull-request page, where I propose a possible solution: https://github.com/obspy/obspy/pull/2093
