Hi,
I'm pretty sure this is the same issue than this one: https://github.com/qgis/QGIS/issues/37898 Long story short, Oracle definition for projection differs from PROJ database ones. So this exception needs to be taken care of. It's done in PROJ > 7.1 but QGIS 3.16 and 3.18 relies on PROJ 6.3.2. When QGIS will be built with PROJ 7.2 or greater (QGIS 3.20 maybe?), il would be OK. But for now, you just have to wait (or build a QGIS 3.18 with PROJ 7.2, not an easy task).
