The LUCI migration app shows the following error: 

@@@SET_BUILD_PROPERTY@luci_migration@{"status": "error", "error": "No module named pyasn1.codec.ber"}@@@

This is after a builder has been flipped to LUCI. Unfortunately, since deleting this builder from Buildbot, the log data is not longer available. 

Assigned to nodir to take a look. 
 

A Buildbot build shows the following LUCI migration app error:

@@@SET_BUILD_PROPERTY@luci_migration@{"status": "error", "error": "No module named pyasn1.codec.ber"}@@@

This is after the LUCI builder has been flipped to prod and this Buildbot builder is still running builds but off-prod. Unfortunately, since deleting this builder from Buildbot, the log data is not longer available.
