The attached test.json.txt shows an error; the attached range_formatting_context.diff (against libadalang_tools) fixes it.

There are additional problems with the response once the assertion_error is fixed; I'll submit another issue.

This issue is now fixed in the the edge branch.
Thank you for reporting and for the reproducer.
