Indeed, this error has been around for a while on debug export templates.

It doesn't impact use however, and it seems to be a false positive (at least the Core API used to build the glue and the template is from the same commit).

@neikeq is aware of the issue, but I don't know if any fix has been tested yet.

For the reference, this is likely still due to #30496, but keeping this issue open as users will look for this error message in the issue tracker.
