DSpace 7.0

[Kosmas Kaifel]

Hi all,

I have installed DSpace 7.0 on Debian  Version 10.
The backendserver works very well.
But when I start the frontendserver (angular) I receive the following
errormessage
from the angular-server.

You may want to double check your Angular UI configurations.  That error almost seems to be saying it's hitting an infinite loop while trying to contact your REST API.

Maybe your "rest" settings in your environment.prod.ts are incorrect, or point at a URL that is redirecting elsewhere?

You also may want to look at whether anything is being logged in the REST API when this error occurs.  More information on troubleshooting DSpace 7 issues is at https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

If you are certain your configs are correct, we may need more information about your setup to help out.  Please make sure to send it to this list, so that others can learn & help!

Hi Kosmas,

Copying the dspace-tech list back in as I am not available for one-on-one support. Please continue to use the mailing list for all questions.

If your Angular UI is hanging (not fully loading), that usually means there's an error on the client side (i.e. in your browser). Often, the problem is that the UI cannot find the REST API (or is being blocked by a firewall or proxy).  So, again, double check your UI configurations (environment.prod.ts settings, especially relating to "rest").  

Keep in mind, UI errors will NOT appear in your dspace.log file, but only appear in the browser.

See the Troubleshooting an error page for how to find the error in your browser. 

https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

Good luck,

Tim

Hey Tim,

thank you for the answer,  but I can not find the problem why start angular not correctly..
The situation at the monent is, that angular start, but not full.

For more information, I have attached the logfile from dspace and the output from
the angular.
Nodeversion:  14.17.4

Yarn:                 1.22.11

The database is from DSpace 7 Beta 4 and this version runs very well on this system.

Best Regards

Kosmas

Hi Tim,

I think the problem that I have is not a problem with the settings in environment.prod.ts or the firewall.

I think the problem is in the angular from from DSpace 7 release, because if I install on the same

system angular beta4 and not the releaseversion the system run very well.

Best Regards

Kosmas

Hi Kosmas,

If it ran on Beta 4 but doesn't run now, it's likely a misconfiguration error.  Between Beta 4 and 7.0 we added additional security, namely CSRF protections.  So, I'd guess you likely are hitting this error or something similar:  https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22403Forbidden%22errorwithamessagethatsays%22Accessisdenied.InvalidCSRFToken%22

Again, I'd recommend looking closer at the errors that are in the client side using this guide: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

I can verify that 7.0 runs successfully as it's running on our demo site at https://demo7.dspace.org/ (using a backend on a different server at https://api7.dspace.org/server/).  I'm also able to run it locally on my machine without any issues.

So, we'd need more specifics on the errors you are seeing in the client side in 7.0.  My guess, based on the info you've provided (that it worked in beta 4 but not now) is that it might​ be a misconfiguration that is causing CSRF protections to distrust your User Interface.  But, that's still just a guess.

Hi Tim,

I found the problem and it was really strange.
Backend- and Frontendserver runs on the same maschine and the Backendserver
runs under https://dspace7-test.rz.uni-ulm.de/server/ with valid certificate.

The access from my local client to https://dspace7-test.rz.uni-ulm.de/server/api is OK,

but the access from the angular to https://dspace7-test.rz.uni-ulm.de/server/api was not OK.

I receive the following message:
ERROR: The certificate of ‘dspace7-test.rz.uni-ulm.de’ is not trusted.
ERROR: The certificate of ‘dspace7-test.rz.uni-ulm.de’ doesn't have a known issuer.

Tim thank you very match for your help.
