03/29/2022, 9:05 PMHi Amit - try running the command from the error message yourself in your command prompt, is it able to launch a Dagster code server? From the error message it seems like it might be hanging or taking a really long time to start up for some reason
daniel
03/29/2022, 9:06 PMwhen we've seen this in the past, it was sometimes because there were side effects in the code while importing causing it to hang

03/29/2022, 9:11 PMHi Daniel,
thank you for quick reply!
Yes, we tried and it kind of got hung and did not proceed. so ended up killing it.

daniel
03/29/2022, 9:13 PMGot it - I think that's your problem. Does that also happen when you run a very simple job? like the one in the tutorial? If not, you'll want to figure out what about your code is taking so long to load
daniel
03/29/2022, 9:14 PMwhat you want is to see a log line like this:
Copy code
2022-03-29 16:13:48 -0500 - dagster.code_server - INFO - Started Dagster code server for module dagster_test.toys.repo on port 4000 in process 66915daniel
03/29/2022, 9:14 PMthat means your code has loaded and is ready fro dagit to talk to it

Amit Pujari
03/29/2022, 9:15 PMokay, but It gets stuck when I am launching the dagster itself, so could not get to the point where a simple job can be executed

daniel
03/29/2022, 9:16 PMCould you say more about what exactly is getting stuck? What command are you running, and how long are you waiting before killing it?

03/29/2022, 9:22 PMokay so to launch dagster we have .bat file with cmd command to call dagster-daemon and call dagit. after execution the error is
2022-03-29 162121 -0500 - dagster.daemon.SensorDaemon - WARNING - Could not load location repository_local.py to check for sensors due to the following error: Exception: Timed out waiting for gRPC server to start with arguments: "C:\Users\YBH7957\Envs\khde\Scripts\python.exe -m dagster api grpc --lazy-load-user-code --port 59813 --heartbeat --heartbeat-timeout 120 --fixed-server-id 08aaa9a7-1172-486c-95c8-4a0d0892b371 --log-level WARNING --use-python-environment-entry-point -f kh_dagster/repository_local.py -d C:\Users\YBH7957\PycharmProjects\khc_data_eng_core".

daniel
03/29/2022, 9:22 PMgot it. I think the first thing you'll want to figure out is why your code is hanging when it loads
a
Amit Pujari
03/29/2022, 9:23 PMand when tried executing this command from cmd directly it's still hung after waiting for 5 mins
d
daniel
03/29/2022, 9:23 PMin the past i've seen that happen because it was hitting postgres on import, or sometimes Azure Key manager on import, things like that, and it was hanging or taking forever
daniel
03/29/2022, 9:23 PMthe hang is very likely due to something specific to your code vs. something in dagster (you could very that by trying to load a very simple job and seeing if it hangs)
a
Amit Pujari
03/29/2022, 9:25 PMokay, will try that. but quick observation my colleague, he downgraded his dagster version to 0.14.5 on the same repo and it started working for him
d
daniel
03/29/2022, 9:27 PMIs there any indication of what it's doing when it's hanging?
daniel
03/29/2022, 9:28 PMOr anything I can do to reproduce the problem myself?
a
Amit Pujari
03/29/2022, 9:30 PMhmm.. not sure how? what version of dagster are you on
Amit Pujari
03/29/2022, 9:34 PMokay, tried removing added code and it worked. so it seems it could be due to compiling code
