Apply Assets Package Error

[FaisalAl-Yaseein]

Hello Esri Community,

I hope this post finds you well. I am facing a problem with Utility Network while working on the water utilities data for Mosul City. I have successfully migrated the data using data loading tools to the water utilities foundation schema. After this, I staged the water utilities, but when I attempted to apply the assets package from the toolbox, an unexpected error occurred, hindering further progress.

I would greatly appreciate any insights or suggestions on why this error might be occurring and how I can overcome it. If anyone has encountered a similar problem or knows potential solutions, your guidance would be immensely valuable.

The error message I encountered is as follows:

Could you share a schema only asset package(run change Asset Package Spatial Reference) and the ap_workspace folder that was created?  We do not need data.  

[FaisalAl-Yaseein]

I already did for the target schema, which result in new gdb with the same schema and no data with the projection that we need. when I run the staging of the utility network, it produced a new data set. the next step from references is to apply assets package which its stopped me

It looks like there is a UN in the Asset Package.  There are known issues with this.  You need to remove the UN and the FeatureDataset.

Hi Mike,

I'm also trying to run Apply Asset Package with pre-existing data. I exported my Utility Network to an asset package, modified that asset package with the D_configurations and D_rename tables, and am following the Solutions workflow for creating a new enterprise geodatabase and running Stage Asset Package and Apply Asset Package. Apply Asset Package is failing with the following error: 

AttributeError: 'NoneType' object has no attribute 'text'

Failed to execute (AssetPackageToUtilityNetwork).

 Is there some other workflow I should be following or step I have missed in order to run Apply Asset Package with an existing UN in the asset package? Or some other method of creating a new Utility Network with the data of an old one?

[MikeMillerGIS]

Can you post a screen shot of the error?  What version of ArcGIS Pro and untools are you using?

[IvanDImitrov]

How is that - to remove UN?
If we want to apply the asset package to a .GDB, we need some features, right? 

[MikeMillerGIS]

The asset package A_, B_ table represent all the properties of the Utility Network and are used to construct one.  There should not be a utility network in the asset package.
