[Swift-user] Block task failed: Connection to worker lost

[Jonathan Ozik]

Hi Yadu,

The tar.gz archive is here: https://www.dropbox.com/s/tt3ewapzaf0ygac/run001.tar.gz?dl=0 <https://www.dropbox.com/s/tt3ewapzaf0ygac/run001.tar.gz?dl=0>
I’m also attaching the swift.properties file that I used below.

Thank you,

Jonathan
