hey, we have an image that runs a dagster instance with all of our needed dependencies on it and exposes a dagit endpoint to use. we tried running the image on a new computer and got an error when it ran the command:

dagit -h 0.0.0.0 -p 5000 -m "sample_project"

error:

@chris telemetry error

0.13.1

Any way you can check the contents of the file at

$DAGSTER_HOME/.telemetry/id.yaml

? Is this file empty?

thanks!

Sorry for missing this- yes deleting should also work. The fix is going out in the release today.
