The supplied extension definition isn't valid: 'Uploaded extension package is missing an 'overview.md' file which is a mandatory details asset.

Trying to publish my extension but getting an error:

The supplied extension definition isn't valid:
'Uploaded extension package is missing an 'overview.md' file which is a mandatory details asset.
Try again after adding the file.'

See:

Turns out the required content/details link is in the vss-extension.json, but the asset isn't added to the vsix manifest.

Looks like files: "." causes the assets elements in the manifest to be lost.
