FME Data Streaming .json file (file just downloads)

Hi @sashalockamy

The data streaming service does this for json. If you build ab application that calls the data streaming url you will be able to work with the json response. You could test this using a http caller in fme to call your data streaming service and check the response.

I had this same issue. We wanted to use the Data Streaming service inside a web application, but the return was always a JSON file. To get around this use a JSONTemplater, JSONFormater and write it out to a text file.

See this thread for example of the solution:

The "DataStreaming" with "TEXTLINE" (text file) output seems to work. I used an "AttributeJSONPacker" compound transformer, set the "Packed Attribute Name" to "text_line_data," but still no success. It prompted for a text download. It finally worked once I deleted the "DestDataset" parameter under "User Parameters"->"Published Parameters" and then, when finally publishing to the FME Server, went into the "Edit..." properties of "Data Streaming" and made sure to add the TEXTLINE writer under the empty box for "Include Writers in Stream" It was not there by default. Maybe because I have been messing with this workbench and switching up output for a while. Now it writes straight to the browser. It may not as efficient this way, but it's what my non-spatial API users expect.
