I have investigated the issue across dev, staging, and prod environments, and it occurs consistently when all Submissions are fetched, though not in every call. The error is likely due to a server-side issue in the ingest-core API, possibly related to resource exhaustion, unhandled exceptions etc. I am currently working to identify the exact cause and implement a resolution.

• [X] replicate locally and connect ingest-ui to local resources - issue was noticed
• [X] replicate locally and connect ingest-ui to dev - issue was noticed
• [X] despite enhancing the HttpErrorInterceptor in theingest-ui to handle retries the issue persists. The issue appears to be server-side in ingest-core
• [X] introduce timeout settings in application.properties and test on dev - the issue was still noticed, need to investigate further
