How to resolve a \"protoreflect\" error caused by an invalid import in Go?

Invalid import causes protoreflect error

The project structure provided shows that the prototemps package containing the .proto files is in a separate directory from the reader package where the error is occurring.

The issue arises because the generated .pb.go files from the prototemps package are not imported correctly in the reader package. The specific error, missing method protoreflect, indicates that the package is missing a specific method required for proto.Unmarshal to work correctement.

To resolve the issue, make sure to include the correct import statements in the reader package. This can be done by adding the following line at the beginning of the reader.go file:

<code class="go">import "github.com/golang/protobuf/proto"</code>

This line imports the proto package from the github.com/golang/protobuf repository, which provides the necessary functionality for proto.Unmarshal.

After adding the correct import statement, the code should be able to successfully unmarshal the protobuf message using proto.Unmarshal, and the protoreflect error should be resolved.
