Describe the issue:
Hello,

I am encountering an “is not configured index pattern ID” error when accessing the Discover menu. The problematic index pattern IDs are either non-existent or show empty values. Occasionally, it requests valid index pattern IDs.

which list of index pattern IDs does the dashboard use for querying?
Why are strang IDs being requested?

I appreciate your assistance. Thank you!

I have additional information to share.

I accessed the index pattern at the address below.
https://{opensearch ip}:5601/api/saved_objects/_find?type=index-pattern

The index that caused the ‘not configured’ error (53ebd030-xxx) actually exists.

The same index pattern with ID 53ebd030 can also be found in Dashboard Management > Saved Objects.

As a note, I am using an admin account with an ‘all access’ role, and I can generally access the 53ebd030 index pattern. However, there are times when access is not possible."
