How can I get chaincode error message?

[hoskylucky]

I wrote a chaincode that includes an add operation and returns an error if the "Id" already exists. When using the gateway-api, the Proposal's Endorse method returns an error message, but it is not the error message returned by the chaincode. How can I get the error message from the chaincode?
Here is logs of peer:

How can I get "the asset id4 already exists" message?

Have you unpacked the 'Details' field of the returned error? An example of how to do that can be seen here:

It should be this content in your answer that the questioner asked..

// Any error that originates from a peer or orderer node external to the gateway will have its details
	// embedded within the gRPC status error. The following code shows how to extract that.
	statusErr := status.Convert(err)

	details := statusErr.Details()
	if len(details) > 0 {
		fmt.Println("Error Details:")

		for _, detail := range details {
			switch detail := detail.(type) {
			case *gateway.ErrorDetail:
				fmt.Printf("- address: %s, mspId: %s, message: %s\n", detail.Address, detail.MspId, detail.Message)
			}
		}
	}
