I've not made any migration so I don't know why this happened. Can someone help me?

Try increasing kibana.yml server.maxPayload to a larger value, Configure Kibana | Kibana Guide [7.13] | Elastic

This doesn't help me because I continue having the same error. The idea is good but maybe is not that the parameter that I need to increment. I've tried also to insert savedObjects.maxImportPayloadBytes: 823769735 and savedObjects.maxPayload: as 823769735
