I am encountering this since today

Failed to load mods: ...wn-space-compat-fixes__/mod-compat/outer-rim-updates.lua:29: attempt to index field 'paracelsin-solar-system-edge' (a nil value)
stack traceback:

[C]: in function 'require'
redrawn-space-compat-fixes/data-updates.lua:11: in main chunk

Is it related to this mod or outer rim?

As you may have heard from the Outer Rim dev, we are working on it.

Outer Rim is going through some changes that haven't exactly been finalized just yet, so I can't update the compatibility until that settles down. From my end, the fix for this error should probably be as simple as removing one line of code, but might need to make some changes to accommodate for the rest of the system

Thanks Kryzeth!

Fixed compatibility with v0.20 of Outer Rim, implemented in v1.0.34

Note that the planets in the Outer Rim system have been completely reorganized from previous version, so you might not want to update if you have an ongoing playthrough and have already unlocked any of the planets.

Regardless of mod loadout, the only automatically generated routes should be between Paracelsin/Aquilo and the other planets. Theoretically, nothing else should connect directly to Frozeta/Secretas (this is how the new Outer Rim works without RSC, so I've kept it that way), and no routes should pass through the system either (no overlapping routes)
