add these Auxiliary Variables in Display Render settings:

Scene Path Cryptomatte.

Surface Shader Cryptomatte.

In Output choose NSI File.

Hit Export button.

Searches for the folder where the NSI file was saved.

renderdl the nsi.file.

console output errorbut the cryptomattes did render witouth json.

what I did to fix this issue is by outputing to image file first, then deleting the rendered exr file and leave only the json files then I can use renderdl without problem.
