Saving a template is refused with 'Failed to save markdown, missing title' or '...missing data'

What you are seeing

Saving a template is refused with 'Failed to save markdown, missing title' or '...missing data'.

#Why it happens

Library templates require both a non-empty title and non-empty content.

Fill in both before saving.

Setting	Where	What it does
Global settings → Permissions	-	Controls edit access to the GLOBAL asset store. Which is what governs who may create Global markdown templates. It is shared with diagrams, images, calendar and search because they all use one Confluence custom content t
Global settings → Migration	-	Markdown is not on the tab's exclusion list, so the tab ships.

Limit	Value	What happens
Library import truncation	Title 128 characters, description 250 ch	Dragging page-owned markdown into the template library silently truncates the copied title and description.
New-template catalogue polling	8 attempts, backoff up to 8 seconds each	After creating a template the app polls for the Confluence-side listing to include it, so a new template can take several seconds to appear.

Entries saved within 15 seconds of the previous shown one are collapsed so rapid auto-save

The reference macro contributes nothing to an export in either product.

The rest of this family.
