Getting an error while searching for a registered company

[codeinuit]

Hello.

I'm using the REST api for a node project (because the Node.js api don't provide enough functions to do what i want.), but when i search for a company, i get an serverside error.

Here what i got :

error:
{ Error: cannot GET /dev/api/search?q=Porostase&page_size=10&type=COMPANY (500)
at Response.toError (/home/node/app/node_modules/superagent/lib/node/response.js:94:15)

Error: Could not find MessageBodyWriter for response object of type: java.util.ArrayList of media type: application/xml

\n\n',
method: 'GET',
path: '/dev/api/search?q=Porostase&page_size=10&type=COMPANY' },

My request looks like that :
superagent .get('https://{DOMAIN}.agilecrm.com/dev/api/search?q=Porostase&page_size=10&type=COMPANY') .set('Content-Type', 'application/json') .auth(config.agilecrm.email, config.agilecrm.apikey) .end(function(err, response) { console.log(response); return response.statusCode; });

(I've replaced the domain by {DOMAIN} for confidentiality.)

Can't fetch the list too when i'm using CURL and the exemple request.

Here's what i got with CURL:

curl: (92) HTTP/2 stream 1 was not closed cleanly: PROTOCOL_ERROR (err 1)

Am i doing wrong ?

Thanks in advance.
