Error on startup when enable the taproot overlay channel

[twofaktor]

After updating to v0.18.4 and adding protocol.simple-taproot-overlay-chans=true to enable this feature, I got this error on startup:

[ERR] LTND: Shutting down because error in main method: unable to create server: taproot overlay flag set, but not aux controllers

What am I missing? How do I add "aux controllers"?

Thanks

If you want to use those channels, you would need to use lit v0.14, as there is no business logic in lnd that drives the state of these channels. LND needs an external implementation of an AuxComponents (lit integrates lnd with AuxComponents) in order for it to know how to operate these channels. I'm not sure why it is possible to turn that flag on in the distributed LND.
