"file" fails to detect JSON files with many levels:
$ echo '{"a":{"b":{"c":{"d":[{"e":[{"f":{"g":[{"h":0}]}}]}]}}}}' | file -
/dev/stdin: ASCII text
This has been fixed upstream by increasing the number of allowed levels:
https://github.com/file/file/commit/6511e6f45a534551b0293e82a434e3cd6504066c
I've attached the corresponding patch without the changes in the
debug messages.
