Existing ADX function crashes delta-kusto job

[sflandergan]

I tried to synchronize a schema from a script with an existing database. The database has some tables, materialized views as well as views defined. Unfortunately the latter crash the Job:

Error:  Issue in running job 'push-script-to-dev'
  Error:  Issue parsing script
  Error:  .create-or-alter function with (skipvalidation = "true", view = true) Assets() {
AssetChanges
| where eventType != "assetDelete"

}
    Error:  There should be one-and-only-one Property name but there are 0

My job definition looks like this:

sendErrorOptIn:  true
failIfDataLoss:  true
jobs:
  push-script-to-dev:
    current:
      adx:
          clusterUri: https://<omitted>.westeurope.kusto.windows.net
          database:  dev
    target:
      scripts:
        - filePath:  other-state.kql
    action:
        filePath:  dev-update-v1.kql
#        pushToCurrent:  true
tokenProvider:
    login:
        tenantId: <omitted>
        clientId: <omitted>
        secret:  <omitted>

This is what .show function Assets returns on the current ADX dev database:

"Name": Assets,
"Parameters": (),
"Body": {
AssetChanges
| where eventType != "assetDelete"
| project-away eventType
},
"Folder": ,
"DocString":

This is the same issue as this one.

It is fixed and will be available in next version.

Fixed in 0.14.0.
