JTAG Command causing an error

I tried to run the JTAG port insertion command but following error caused exiting the process. Is it a bug or something missing at my end?

From what I can see it appears to be that Pyverilog (the syntax parser we're using) is detecting a syntax error for your code. If you feel comfortable doing so, please share the relevant Verilog netlist with us.
Regardless I don't believe Fault should crash if Pyverilog encounters a syntax error and I will try my best to fix that posthaste. Apologies for the inconvenience.

I am running the example given in the wiki which is basically taking s27.v through the flow. I ran all the commands but the final command produced the aforementioned issue.
fault tap -l Tech/osu035/osu035_stdcells.lib -c Tech/osu035/osu035_stdcells.v --clock CK --reset reset Netlists/s27.netlist.v.chained.v
Alright, the issue has been fixed. Please try updating your Docker image by invoking docker pull cloudv/fault
.

Now the previous error has been resolved but a newer one has been produced.

@Manarabdelaty We really need to get rid of the automatic osu035 thing. It's causing far more headaches than it's worth at this point.

A workaround for now is to explicitly provide fault synth and fault chain with the liberty file and the cell model file. The instructions have been updated in the wiki. I have went ahead and manually built the Docker container and verified these steps. Please confirm that this works now and apologies for any trouble that this may have caused you.

The spcific issue of JTAG port isertion has been resolved. I really appreciate your cooperation.
