Hi everyone!
I am new to proto3 and loopback4. I want to declare a 2D array of strings in proto3 interface message service: I want the result to be like this: [[""], [""] , [""] ], Kindly help me to solve this, i have searched everywhere but didn't find support of 2D array in proto3.
Thanks

Proto has no support for arrays with more than one dimension. Therefore you'll need to create an array of arrays. Or in proto terms, a repeated field of a proto message, where that message has a repeated field of strings.

Example:

message RowOfStrings {
repeated string row = 1;
}

message ArrayOfStrings {
repeated RowOfStrings col = 1;
}
