Error on homepage

[Jaware]

Dear all,

Just installed DSpace 7.1 over Ubuntu and able to  connect to the REST API by running yarn config:check:rest works fine and runing  yarn start also works.

I  can login to the angular interface however I was looking the following errors

at the home page (error.top-level-communites) and also the following error while I was creating top level communtiies(An error occurred searching for a community

Request is invalid or incorrect)

May I get your support please

Testing the rest fine

jaware@library:~/angular-dspace# yarn config:check:rest

Building production environment

No specific environment file found for --prod

Angular environment.ts file generated correctly at ./src/environments/environment.ts

...Testing connection to REST API at http://172.21.6.150:8080/server/api...

RESPONSE: 200

Checking JSON returned for validity...

        "dspaceVersion" = DSpace 7.1

        "dspaceUI" = http://172.21.6.150:4000

        "dspaceServer" = http://172.21.6.150:8080/server

        "dspaceServer" property matches UI's "rest" config? true

        Does "/api" endpoint have HAL links ("_links" section)? true

Done in 3.77s.

Best,Jaware

Hi,

I'd recommend checking your UI and backend for possible error messages.  Here's a troubleshooting guide for how to do that: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

We also have several common error messages that may be found (in either the UI or backend) documented here: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues

Chances are you are hitting one of those common configuration issues (which may not be detected yet by the "yarn config:check:rest" script yet).  If you find the more specific errors in the UI or backend logs and cannot figure out a solution, feel free to send them to this list and we'll provide further advice.

Tim

Hi Tim,

I just seen the error on chrome browser which looks like the following.Can you suggest me the solution as per the following error

 Environment: Production
:8080/server/api/config/properties/google.analytics.key:1 Failed to load resource: the server responded with a status of 404 ()

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

Wed Nov 10 12:42:36 UTC 2021

There was an unexpected error (type=Not Found, status=404).

An exception has occurred

Thanks,Jaware

Hi Jaware,

The messages you sent in your last email can be ignored safely as they are not the root problem.  

The 404 response from "google.analytics.key" is just saying that you haven't yet configured that configuration on your backend. It will not cause any problems & can be ignored.

The "Whitelabel error page" just tells us that page is not responding but doesn't give us any information as to why it is not responding. 

So, in both cases, you need to look for a more descriptive error in your Browser's DevTools or in the backend logs.  Again, please see our troubleshooting guide for step-by-step of how to find more information about the errors.  https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

Until you find the underlying errors, we won't be able to provide any useful support or help.  My best guess is that you are likely hitting one of the common installation issues, but I don't know which one until you follow the troubleshooting guide & look for errors.   https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues

Hi Tim,

Thanks for your concern.

Here attached log files from both dspace and tomcat.

Let me know if something is figured out.

Thanks,Jaware

Hi Jaware,

Your DSpace log shows this error:

java.lang.RuntimeException: Error from server at http://172.21.6.150:8983/solr: Expected mime type application/octet-stream but got text/html.

That error is documented in our "Common Installation Issues" guide which I linked to. See https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-Solrrespondswith%22Expectedmimetypeapplication/octet-streambutgottext/html%22(404NotFound)

​

Please also keep in mind that, because the DSpace 7 UI is Javascript-based, there are some errors that may ONLY APPEAR in your web browser's DevTools and never be sent to the DSpace or Tomcat logs on the backend.  This is why I keep stressing that you need to follow the "Troubleshooting" guide around using your Browser's DevTools to look for errors in your browser.  When you do so, it's possible you'll see other issues mentioned in our "Common Installation Issues" which will be quick for you to resolve on your own.  

Therefore, please make sure you also look for these Browser specific errors and check the Common Installation Issues list to see if you have encountered an easy to fix error.  Here's that "Troubleshooting" guide again: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

(See the first section on "Finding the Error Message in the User Interface" for information on locating errors that only appear in your web browser)

Overall, I suspect that the issues you are experiencing are all configuration problems & not bugs in DSpace. The errors you find will guide you in the direction of which configurations need updates.  Let us know on this list if you find an error that you are unable to locate the solution to in our "Common Installation Issues" guide.
