Hello @Eddynson Vega ,
Thanks for the question and using MS Q&A platform.
My understanding is that you are receiving the above error while trying
data preview a JSON file as source in Mapping Data flow. But when you tried the same source in Copy activity then there no issue, which confirm you that there is nothing wrong with data. Please correct if I misunderstood the ask.
If the above understanding is correct then, it seems like there is something wrong with your source settings configuration in Mapping data flow source.
We recommend to please make sure the
JSON Settings under
Source Options tab are correctly configured.
Before previewing the data, please correctly configure the
JSON settings under
Source Options tab and then under
Projection tab check if you are able to see the schema if not try
Reset Schema or
Import projection. And then try to preview the data.
I tried to reproduce the issue but no luck. In case if the above steps didn't help to resolve your issue, we request you to please share a sample JSON file (Please note: save the JSON file as TXT extension to attach here) attached in your response along with screenshots of your
Source options (exand JSON settings),
Inspect tab settings which would help us to reproduce the issue on our end.
Hope this will help. Please let us know if any further queries.
