Error when setting zero fee and rebalance channel

Hi,

We have an issue in our triangle. I have set the fee policy to zero on my out going channel but when the receiving peers is trying to set the inbound fee to zero on my outgoing channel there is an error message-

Update Channel Failed
Error Code
500
Error Message
channel from self node has no policy
API URL
./api/lnd/channels/chanPolicy

When I try circular rebalance with RTL following the instructions I get the following error message when estimating price

Get Query Routes Failed

Error Code
500
Error Message
unable to find a path to destinationAPI URL
./api/lnd/network

Any advice on what to do?

Thanks
