Rebalance plugin errors out

Hello. First things first.

C-Lightning Version: v0.10.2 Debian BullsEye on a RockPro64 single board computer

I’m trying to rebalance a channel and I set the fees for the 2 participating channels to base=0 and ppm=0. The channel I want to rebalance is 1,426,049 sats on the remote side and 23,951 sats on local side.

The other channel is 1,523,465 in local side and 52,352 on the remote side.

I already tried a few different combinations of maxfeepercent and retry_for parameters. Also tried with no parameters but in_scid and out_scid but I always get one of 2 errors that I’ll paste here at the end.

The commands I already tried were:

lightning-cli rebalance -k outgoing_scid=665969x1380x0 incoming_scid=690200x2004x0

lightning-cli rebalance -k outgoing_scid=665969x1380x0 incoming_scid=690200x2004x0 maxfeepercent=0.1 retry_for=180

I tried a few percent values here, up to the default of 0.5. I also tried different retry times, up to 600s

I also tried with fees different from 0 but I always get the same errors.

Error 1:
