User picker error when trying to assign a user to a field such as "Assignee"

[Abi]

Whenever I try to assign a ticket to a person from the drop down menu, it throws an error:

"The Jira server was contacted but has returned an error response. We are unsure of the result of this operation"

From the logs

/rest/api/latest/user/assignable/multiProjectSearch [c.a.jira.permission.DefaultIssueUserSearchManager] Requested top N=200 and is greater then max top allowed: 100

How do I go about updating the requesting number from 200 to 100. It seems like whenever I try to assign an issue to a person, it is pooling more users than it can hold. 

Using jira 8.22.6

@Abi, 


I found this KB which may be of use in your scenario. Can you please review and try the solutions outlined in the article?

Thanks,

Kian

Thank you for your quick response. 

Yes I have seen that article and tried its workaround. However, that did not really work. The first method was making smaller groups, I don't think that is feasible in my situation. The second method, increase the number of groups to look through. That is not my problem, as its there are more users in a group than is allowed to be showen in the drop down.

@Abi,

That error lines up perfectly with what is shown in the KB. Is there are second line that shows similar to the following:

Nope, here is the error logs.

Have you tried increasing the number of batches?

[Abi]

Yes I have. Do you know any other related JVM arguments that are similar to the number of batches.
