which version of node.js are you running?

Apr 02 '18 08:04 rorydavidson

node version v6.11.4

Apr 02 '18 09:04 009topersky

Not sure where the error is coming from as it is working ok on ubuntu with node.js versions 5 and above.

However, just completed a version using docker containers which you can find on the develop branch - https://github.com/IHTSDO/sct-snapshot-rest-api/tree/develop. This might bypass any issues that running node.js on Windows may be introducing.

Good day sir!

Currently i'm working on Windows 10 Environment

still i have the issue and i'm stuck :(

Apr 02 '18 10:04 009topersky

Moving forward.,

how can i get the 1.3 version of rf2-to-json-conversion

https://github.com/IHTSDO/rf2-to-json-conversion NOTE ensure you are using versions 1.3 and above of the conversion tool to create the JSON files. Older versions will not work.

Apr 02 '18 10:04 009topersky

You can find it here - https://github.com/IHTSDO/rf2-to-json-conversion/releases/tag/1.3

Hi, I had this problem earlier as the status code was returning as text instead of code. You need to make changes to your app.js at 2 places i guess

In place of (pls comment the below portion) /res.send('error', { message: err.message, error: {} });/ And change it to the below statement res.status(err.status >= 100 && err.status < 600 ? err.code : 500).send(err.message);

This should work

@rorydavidson , using the development branch, now I have the message from the server (RESTful API) "There are no data for this conceptId:". The concept id I was looking for is in the mongo db, but not returning a valid response from the server.
