We use the REST connector configured to "Ignore error and continue process" so the process can check the HTTP response code itself, get the error response body, and report it gracefully to the user.

However, the connector does not fill any outputs if the connector sees the HTTP error code is not 2xx or 3xx, as you can see in RESTConnector.execute():

            if (!statusSuccessful(statusCode)) {
                throw new ConnectorException(
                        String.format("%s response status is not successful: %s - %s", request, statusCode, httpResponse.getStatusLine().getReasonPhrase()));
            }
            setOutputs(httpResponse, request);

The fix would be to move setOutputs() before the exception is thrown (above if), so outputs are always set for the process to analyze.

Hello please can'i have your support on building the project ? Here is the process i followed.

$ git clone https://github.com/bonitasoft/bonita-connector-rest.git
$ cd bonita-connector-rest/
$ mvn clean verify

But i'm facing this issue :

[INFO] Scanning for projects...
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM for org.bonitasoft.connectors:bonita-connector-rest:1.0.5-SNAPSHOT: Failure to find org.bonitasoft.connectors:bonita-connectors:pom:1.0.0 in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM @ line 4, column 13

What i'm doing wrong ?

For example, Bonitasoft BPM server returns this from a login request:

Server: Apache-Coyote/1.1
Set-Cookie: bonita.tenant=1
Set-Cookie: JSESSIONID=FDFB2C8CD28C6C13222FE49E2C1DC32F; Path=/bonita; HttpOnly
Set-Cookie: X-Bonita-API-Token=6c4698ce-3e25-407d-8c40-cdab15a63aad; Path=/
Content-Length: 0
Date: Thu, 26 Oct 2017 10:25:55 GMT

Here, the "Set-Cookie" header is repeated 3 times. The RESTConnector.java file will convert Header[] to a Map, but one key maps to one value, and so only one "Set-Cookie" header will remain.

The problem code is here (below). My recommendation would be to return an array of values, if there are multiple.

We have a web service that returns a numeric value as a response.
The REST connector assumes that the response is either an array of objets or an object, in this case trying to deserialize json into a Map which is resulting in an exception.

The connector should not raise an exception when the response is a simple value (string, number, null, true, false, date).
