Hi, At least according to my reading of the code, I believe that "requests" directory should be recreated after it is deleted (which occurs during clearing the cache).
In the OAI caching code, you can see the "requests" directory is returned "getBaseDir()" here: https://github.com/DSpace/DSpace/blob/dspace-9_x/dspace-oai/src/main/java/org/dspace/xoai/services/impl/cache/DSpaceXOAICacheService.java#L44 And, here, that directory is re-created if it doesn't exist: https://github.com/DSpace/DSpace/blob/dspace-9_x/dspace-oai/src/main/java/org/dspace/xoai/services/impl/cache/DSpaceXOAICacheService.java#L73-L76 I'd recommend looking closer at the 500 "Internal Error" you are receiving. 500 errors are very generic errors that just mean "something went wrong". To determine what actually went wrong, you'd want to use the Troubleshooting Guide <https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error>to look for a more detailed error message. In this case, it's likely the more detailed error behind that 500 error would be in your DSpace logs or Tomcat logs. If you are able to verify that the 500 error is being caused by the missing "requests" directory, then I'd recommend creating a bug ticket in our GitHub repository <https://github.com/DSpace/DSpace/issues> and describe the exact steps you took, and share the detailed error message that you found in your logs (when that 500 error occurs). Hopefully that helps, Tim On Tuesday, February 17, 2026 at 4:31:51 AM UTC-6 [email protected] wrote: > Hi Tim, > > I currently have the same problem, "oai import" deletes the "requests" > directory, and further OAI client requests face 500 "Internal error" > > Are you sure it is later recreated?
