Bidireconal Switch Assertion failure: dst != WireId()

[maxall41]

Apologies if this is the wrong place to post this I'm pretty new to icestudio and FPGAs in general.

Im trying to create a bi-directional switch on an I2C data line but I can't seem to get it to build no matter what I do I always get the error:

libc++abi: terminating with uncaught exception of type nextpnr_ice40::assertion_failure: Assertion failure: dst != WireId() (/work/_builds/darwin-x64/nextpnr-ice40/nextpnr/ice40/delay.cc:160)

whenever I try to build my code. I have attached the icestudio file and a screenshot of my design is below. Does anybody know why this is happening?

What is your board?

I'm closing this issue for no feedback received. No in the last wip https://downloads.icestudio.io you could use inout ports that do easier the use of tristate ports.

If you need something more, reopen it.
