thanks, I got around that problem. I run into
DEBUG:asyncio:poll 573.300 ms took 0.016 ms: 1 events
DEBUG:asyncio:process 21691 exited with returncode 1
INFO:asyncio:<_UnixSubprocessTransport pid=21691 stdin=<_UnixWritePipeTransport closed fd=17 closed> stdout=<_UnixReadPipeTransport closed fd=18 closed>> exited with return code 1
DEBUG:asyncio:poll 563.276 ms took 0.014 ms: 1 events
DEBUG:asyncio:process 21692 exited with returncode 1
INFO:asyncio:<_UnixSubprocessTransport pid=21692 stdin=<_UnixWritePipeTransport closed fd=19 closed> stdout=<_UnixReadPipeTransport closed fd=20 closed>> exited with return code 1
INFO:asyncio:poll 999.912 ms took 1001.039 ms: timeout
I can run the solver manual and it seems to work. Is there an easy way to see the output/error of the solver so that I can keep debugging?
