Issue description

See: https://github.com/godotengine/godot/actions/runs/12211086323/job/34068068226?pr=100135
Using TypedDictionary<>() will lead to failture of godot-cpp compilation. Needs to be fixed as soon as possible.

Steps to reproduce

Using a TypedDictionary in source code and push it to your forked repo, and then run the action on your fork.

Minimal reproduction project (MRP)

Reproduction = source code. See Steps to reproduce

I'm not sure this is a Godot issue? The format looks ok, typeddictionary::Key;Value, are you using the latest GodotCpp? It should support them since this PR godotengine/godot-cpp#1162, expecting the format for example here. Otherwise that would be a GodotCpp issue.

Could be because the CI checks against 4.3

Yeah, we use the previous version of godot-cpp in the Godot tests to avoid circular dependencies between Godot and godot-cpp changes.

But updates to extension_api.json are tricky, and if this is the issue, we may need to either (1) use a particular commit from master in the Godot CI, or (2) merge something to the 4.3 branch of godot-cpp that allows it to not generate bad code when there's a typed dictionary in extension_api.json (it could just use Dictionary?)

I feel like we should have had this same problem with typed arrays, but I don't recall if we had to do anything to for that?

Typed arrays were introduced a long time ago, not sure we had any checks for extensions back then
