Issue in mapping json file with comment

[cd160]

I am trying to map data out of a JSON file. However, my file has comments at the beginning. If I remove them, job runs smoothly with no issues.

However, If I use the file as is with the comment, my log comes out blank.

The job design is quite simple:

tFileInputJSON->tLogRow

Eventually the main job is to map the JSON file columns into MongoDB (tFileInputJSON->tMap->tMongoDBOutput), but that was not a problem. Again, the job runs smoothly when I remove the comment at the beginning.

Below is how the file starts, including the comment at the beginning in RED.

Hopefully someone can advise.

Thanks!

Hi
If the file always has the same number of lines, you can use tSampleRow to remove the comments and create a new file before extracting JSON data, eg:
tfileinputFullRow--main--tSampleRow--tFileOutputDelimited
|
onsubjobok
|tFileInputJSON->tMap->tMongoDBOutput

on tSampleRow: set the Range as: ""23..36""
