Unexpected token B in JSON at position 0

[vroger11]

I just wanted to try your API. After installing everything like in the README, I get an Unexpected token error on the example given in the README. Any help will be great, thanks.

All informations (also, I used the version tagged "v1.0"):

This is because the ReadMe is not yet customized. Sorry for the confusion. I will adapt the ReadMe shortly. We have now implemented the geocoding in the frontend via Mapbox and pass a BoundingBox to the API. So your request must look like this:

http://127.0.0.1:8000/v1/water/?from=2020-04-10&to=2020-04-20&location=[32.4371337890625,25.809781975840405,32.92877197265625,26.251546424213046]

If you want to re-enable geocoding via the API, all you really need to do is uncomment lines 36 through 40 in the serializer.py, and change line 57 to this:

bbox=bbx,

This should work.

Ok thanks for your answer, I will look into it asap

[NiklasJordan]

@vroger11 Does it work for you?

[vroger11]

Thank you for the reminder. I forgot to check it (I am deeply sorry). It works using your intel! It definitively needs to be specified in the README.
