FHIR resources cannot be created

[LUU LAM CHI PHAT]

Hi,

I am currently using our hapi-fhir server to test my website which uses the FHIR resources, but today when I come to log into my website that have used our server, my website returns a "Timer already cancelled" error message. I am looking forward to receiving your reply on the solution to this issue.
{
  "error": "FHIR cannot be created",
  "detail": "{\n  \"resourceType\": \"OperationOutcome\",\n  \"text\": {\n    \"status\": \"generated\",\n    \"div\": \"<div xmlns=\\\"http://www.w3.org/1999/xhtml\\\"><h1>Operation Outcome</h1><table border=\\\"0\\\"><tr><td style=\\\"font-weight: bold;\\\">ERROR</td><td>[]</td><td>HAPI-0389: Failed to call access method: org.springframework.dao.InvalidDataAccessApiUsageException: Timer already cancelled.</td></tr></table></div>\"\n  },\n  \"issue\": [ {\n    \"severity\": \"error\",\n    \"code\": \"processing\",\n    \"diagnostics\": \"HAPI-0389: Failed to call access method: org.springframework.dao.InvalidDataAccessApiUsageException: Timer already cancelled.\"\n  } ]\n}"
}
Any ideas about this error
Best regard!
