With the current installation (ConTeXt  ver: 2024.12.30 16:14 LMTX  fmt: 2025.1.24  int: english/english), I am hiting this error:

can you change this at the end of util-json

package.loaded["util-jsn"] = json
package.loaded.json        = json

return json

and remake the format?

(the json module is now always preloaded)
