Importing full v13 pack into v15 misses a lot of templates

[PhyxionNL]

Describe the bug
A clear and concise description of what the bug is.

Version (please complete the following information):

• Umbraco Version: 15.0
• uSync Version: 15.0
• uSync.Complete Version: 15.0

To Reproduce
Steps to reproduce the behavior:

1. Export a full sync pack in uSync in v13 installation.
2. Create v15 project.
3. Import v13 into v15.
4. I only get 5 templates in Umbraco. All the other content seems to be imported OK. Weirdly it does report 70 templates in the progress thingy, but only 5 are added.

Expected behavior
Get all templates. It works OK to import v13 pack into a blank v13 and then upgrade Umbraco.

Hi,

Can you send a screen shot of the structure ? is there any noticible logic, (it might be failing on children for example?)

Also does a second import bring them in (just wondering).

I didn't find any logic, I've tried it a couple of times and it are always the same items that are imported.
When it's processing "Content", I do see a lot of these in console:

[13:10:34 INF] The reference to umb://media/695a51117c694d1e8629451d9acf1ab7 can not be saved as relation, because doesn't have a node ID.
[13:15:16 INF] The reference to umb://document/9aa809248d6d41d69124bf3be81ee9cb can not be saved as relation, because doesn't have a node ID.
[13:15:18 WRN] no json images found for []

Screenshot:

It says all these templates are imported, but they're not listed in Umbraco under Templating > Templates, and not bound to the Document Types, so Umbraco complains about missing templates.

The templates in the exported zip file look the same compared to the ones that are imported.

Also does a second import bring them in (just wondering).

Sadly not, it has the same issue. I also tried Import (Force).

yeah - you can disregard the relation errors (that's an umbraco issue, it happens when you install the starter kit on a blank site) 😞

I will take a look see if this is anything i can reproduce.
