Error, Entity not found

[beks-sudo]

For over 3 months now my smart home actions project has been working nicely until devices could not get state reports. Usually, I will unlink and link, and everything works again. But now I cannot link my account and GCP logs says,

{ insertId: "1sxo31kfx6qkt9" jsonPayload: { syncLog: { syncs: [ 0: { httpLatencyMsec: "476" requestId: "10916225480411519889" status: "INVALID_ARGUMENT" } ] } } logName: "projects/--------/logs/assistant_smarthome%2Fassistant_smarthome_logs" receiveTimestamp: "2021-06-04T21:20:03.936849419Z" resource: {…} severity: "ERROR" timestamp: "2021-06-04T21:20:03.936849419Z" }

and my node application also gives an error that says

{ "error": { "code": 404, "message": "Requested entity was not found.", "status": "NOT_FOUND" } }

Please help me
