Rudder

An archive that was exported from Rudder 8.0.6 cannot be imported back into a fresh Rudder 8.0.6 server.

The import error message is :

{"action":"import","result":"error","errorDetails":"error when committing Technique '*REDACTED*/1.0'; cause was: Unexpected: Error when trying to compile technique '/var/rudder/configuration-repository/techniques/ncf_techniques/*REDACTED*/1.0'. Error details are available in `compilation-output.yml` file in the same directory. Error message: 'Exit code=2 for technique: '/var/rudder/configuration-repository/techniques/ncf_techniques/*REDACTED*/1.0'.'"}

The compilation-output.yml file contains :

compiler: rudderc
fallbacked: false
resultCode: 2
fileStatus: []

It seems that Rudder could save an export a technique with an unnamed, undescribed and unused parameter, but that importing back the same technique will fail with a control that a parameter has a valid name.
