Error in creating app template with App Engine Studio

[Moritaka Kanai]

Hi. I'm always encountering the following error when creating an app template:

CREATE A TEMPLATE
A template can't be generated from this app.
Something from this app isn't supported in a template. Learn more about custom app templates.

According to the manual, the possible outcomes here should be "All the objects are supported", "Few objects aren't supported", or "Few objects are denied". But the error message above is none of these.

Am I missing something?

Vasantharajan,

Thank you for your note!

In my case, the following "deny_reason" has been indicated:

<response>
<result>
<templatizable>false</templatizable>
<deny_reasons>App has records that may not be supported: sc_cat_item_producer</deny_reasons>
</result>
</response>

After deleting the relevant row from sc_cat_item_producer table, the template creation has successfully been completed.

Thanks!

Since the error cause "sc_cat_item_producer" is one of the supported features and metadata in custom templates according to docs, I have filed another question:

What if the deny reason of creating an AES template is one of the supported features and metadata in...
