When i execute the below command i'm getting the following error, this problem doesn't come normally , but when i have more set of json files (probably one of the json file format might not correct , but how to identify that), please assist in solving this issue.

$ istanbul report text --root merge6/ --dir jsonfilesreport/ -v
