Hello All, I am trying to install Datahub (v0.9.2) on GKE clusters. I am able to open the front-end service running on the port 9002 but when I try to access the GMS service running on the port 8080, I get the below exception:

hey there! when you say access gms at 8080, what do you mean? as in your frontend service tries to make a request and you see these errors? or do you mean try to access it through the browser by going to http://localhost:8080/?

@bulky-soccer-26729 - Hey Chris! I will remember to post my logs in threads going forward. Reg. your question on how I access the GMS, I tried accessing via browser http<ip address>8080 and also tried connecting to GMS using the GreatExpectations integration where we mentioned the GMS URL in their yaml file. In my case, I was unable to see the expectations from GE under the “validations” tab for the particular table.

ahh gotcha - yeah so we don't expose 8080 to be accessed on the browser like that - that's why you're seeing that error on the browser. if you're able to run the app through the frontend and interact with things / see data then GMS should be up and running just fine! (especially if there are no logs in GMS specifically saying otherwise). As far as the great expectations integration goes, it sounds like something is off with how that's set up instead of GMS being the problem here is my guess. I assume you've read through the docs on that here?

@limited-sundown-13355 Were you able to get past this issue?

Thanks for the response @bulky-soccer-26729. Yes, in my case, am able to see the app running, connected to BigQuery tables and details like lineage appears ok. But my validations tab is failing due to the failure with the GE integration. Yes, I did follow the link shared by you. Let me re-try it one more time.
