ERROR: INVALID DSPACE REST API! Response is not valid JSON!

[Lewatle Johannes Phaladi]

Dear Dspace Team,

logging into dspace frontend continues endlessly, I have checked logfile and attached copies of most files and screenshots that might be helpful for you to assist on this problem. 

Please see attached items, as follows :

1. dspace.log 

2. yarn config:check:rest screenshot : API test results X 2

3.  environment.prod.ts 

4. Frontend login error screenshot 

Regards,

Lewatle

Hi Lewatle,

From the response to "yarn config:check:rest", it appears your REST API is responding oddly...it seems to be breaking up the response into "chunks".

The response from "yarn config:check:rest" should be a single​ response, whereas your site seems to somehow be returning JSON split apart into 3-4 chunks (as you can see it keeps showing "Response returned" several times, instead of just once) .... this seems to have the side effect of the JSON being seen as invalid, as it doesn't come back in one piece.  If it's not obvious, the DSpace User Interface expects the JSON to be returned in one piece.

I must admit, at this point, I'm not sure what could be causing this.  Maybe something in your Tomcat setup? Maybe there's some sort of proxy or firewall between your UI and REST API that is causing the request to get mangled?

I've never seen this sort of behavior from a DSpace 7 REST API before, so I'm a little confused.  I don't know how this can be occurring.

Another option here might be to try an installation of 7.2 (which is the latest) to see if that solves the problem you are seeing.  It sounds like you are currently trying to install 7.1.  Maybe starting fresh with 7.2 will help out here, as there seems to be something odd going on with your current setup.

Tim
