Browse page doesn't load. Console gives a 500 error code

Rob Sizeland shared this question ago

Awaiting Reply

Hello,

I've created a Yellowfin instance for a customer, but upon importing all the reports the browse page refuses to load.

I can get around it by deleting the forever loading overlay in inspect element so I can go to the Admin console. But anything that opens the browse page (such as Timeline), I get a 500 error in the console when trying to add a report to a post.

It's a completely fresh install of Yellowfin, the customer hasn't interacted with it at all. The only thing I have done so far is add the datasource, views, dashboards and reports. I have done this twice as the first time I thought maybe it was because the AMI used was old so it didn't have the newer updates. But I have used a new AMI that we use with other clients that work fine.

In the logs the only error I can see when trying to go to the browse page is:

YF:2023-11-14 09:56:23.790:ERROR (ContentProcess) - [62] [DA783981] [/BrowseAjax.i4] com.hof.util.ActionErrorsException: java.lang.NullPointerException

com.hof.util.ActionErrorsException: java.lang.NullPointerException...

Any help is appreciated.

Hello Rob,

I hope this email finds you well. Thank you for joining the call earlier. We appreciate your time and collaboration.

During our discussion, we identified that the Dashboards and reports are functioning properly; however, we noticed a delay in page loading. Upon page inspection, we observed an internal server error (500) occurring during the page load process.

To investigate this issue thoroughly, we kindly request you to provide us with the complete logs. Could you please zip these log files and upload them to our FTP server? Additionally, ensure that you attach the "info.jsp" file and specify the file name.

Hello Rob,

Greetings of the Day!

Upon investigation the logs, it appears that an invalid header is being rejected, that there's an issue with your recent API requests, resulting in an internal server error (500).

YF:2023-11-16 07:30:17.395:ERROR (AuthenticationInterceptor) - [40] [Background] [/api/.env] Request http://3.106.82.137/api/.env was rejected - INVALID_HEADER

To resolve this matter swiftly, could you kindly review and adjust the headers included in your API request? Ensuring that the headers are correctly formatted and valid should rectify the issue causing the internal server error.

Furthermore, we would greatly appreciate it if you could provide us with specific details regarding the API and function you are currently utilizing. This information will help us where the exact source of the problem and expediting the resolution process.

Hi Vamsi,

I'll take a look and see what I can find. I just find it odd how it can suddenly change/break the header by just importing reports/dashboards.

If it was an issue with our API request, shouldn't this affect all our clients Yellowfins as they all use the same version build. Wouldn't the invalid header also cause all the other pages to stop working, instead of just the browse page?

I'll update you when I've checked our API request as the files are showing as not being modified...

Many thanks,

Rob

Hi Vamsi,

There are no API calls being made as it's just logging in to Yellowfin and redirecting to the browse page.

There are no altered files either.

Many thanks,

Hi Vamsi,

I'll also add that during the screen share we did, you yourself saw there were no API calls being made as we were just logging into Yellowfin directly.

Many thanks,

Hello Rob,

I hope this message finds you well.

Following our recent discussions with our internal technical team regarding the issue you've been experiencing, we've thoroughly reviewed the logs and examined the `info.jsp` file. It has come to our attention that the Java headless configuration is currently set to true.

d3f02b29de5a451ba443ff5440dc9806

At this point I would recommend taking the following steps:

1. Uninstall the current 'openjdk-8-jre-headless' package and install the complete package of openjdk-8-jre

We believe this change might positively impact the situation. Once the new configuration is in place, please inform us of the outcome.

To update the new java package please follow the link shared below.

https://community.yellowfinbi.com/knowledge-base/article/how-to-change-yellowfins-java-path-windows

Note: Please stop the running tomcat server and install the full package of open JDK JRE. once the changes are updated please start the tomcat server and login to Yellowfin UI.

Regards,

Hi Vamsi,

I've done what you've said, but it's still 500'ing at the browse screen. We found out about the headless issue when charts wouldn't load correctly and doing that fixed it. But this isn't the same problem.

I've checked it's the full JDK JRE now instead of headless and the JRE_HOME is correct.

Is there anything else that could be causing the issue?

Many thanks,

Rob
