[Lists] [Eureka bugfest] 502 in the network after running queries which are supposed to return big amount of records

ENV:

• Eureka ECS - https://eureka-bugfest-ramsons-consortium.int.aws.folio.org/lists/new

• Eureka non-ECS - https://eureka-bugfest-ramsons.int.aws.folio.org/

PRE-CONDITION:

• The admin user is logged in

• The admin user is on the “Lists” landing page

STEPS..

1. Click on “New” button on the landing page

2. Add a listname, select a record type - “Holdings”

3. Click on “Build query”

4. On the QB, select the field “Holdings — UUID”

5. Select the operator “is null/empty”

6. Select value - “false”

7. Click on “Test query”.

ACTUAL RESULT:

• This query is supposed to return more than a milion records and probably due to that, the proper API request sometimes returns 500 or 502, this behavour is not stable, as you can see in my screenshot, the other requests are successfull, and several minutes they fail again

• This query doesn’t return any value on Eureka non-ECS, I waited for ~ 1 h. On the Eureka ECS, we have the same errors, but after ~ 8-10 min, I am getting a result

EXPECTED RESULT:

• No errors on the network

• All requests are successfull, after few min the query returns the result

NOTE:

• Everything looks good on OKAPI ECS and non-ECS environments
