ConnectorError Prisma with MongoDB - mongodb

Question

I am developing an API with Nestjs and MongoDB. Well sometimes I have this problem. It doesn't always happen and that's what I have to solve because this error rarely happens.
This is the error:
{
"status": "error",
"message": "\nInvalid this.prisma.people.findMany() invocation in\nC:\ima\empresas\datec\api-official\src\modules\Events\services\utils.service.ts:57: 28\n\n 54 }),\n 55 \n 56 // Get attendees by id\n→ 57 this.prisma.people.findMany(\nError in batch request 3: Error occurred during query execution:\nConnectorError(ConnectorError { user_facing_error: None, kind: RawDatabaseError { code: "unknown", message: "An existing connection was forced to be terminated by the remote host. (os error 10054)" } })"
}
I really can't find much information to solve this error. I have followed the steps in the documentation on Nestjs when using prisma with nestjs. I need help to solve this error, since it is essential to find a solution as soon as possible. Thanks so much for read this question

this.$on('beforeExit', async () => {
