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

Hello Rob,

Thanks for your quick response. Sure, Please check and let us know how it goes.

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,

Rob

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,

Rob

Hi Vamsi,

I haven't heard back from you and we are still having this issue.

We would like to get this resolved for the customer ASAP, so if there's anything else we can provide please let me know.

Many thanks,

Rob

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.

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.

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.

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
