IO error: lock _replicator/LOCK: Resource temporarily unavailable

When attempting to run pouchdb-aws-serverless (https://github.com/KouchDB/pouchdb-aws-serverless), I am getting this error:

{
"errorType": "Runtime.UnhandledPromiseRejection",
"errorMessage": "OpenError: IO error: lock _replicator/LOCK: Resource temporarily unavailable",
"reason": {
"errorType": "OpenError",
"errorMessage": "IO error: lock _replicator/LOCK: Resource temporarily unavailable",

},
"promise": {},
"stack": [

" at processPromiseRejections (node:internal/process/promises:274:27)",
" at processTicksAndRejections (node:internal/process/task_queues:97:32)"
]
}

I need someone to give me the solution to fix this error.
