MATLAB rosgenmsg() Issue with zed_interfaces

[jaronski]

when trying to get zed_interfaces custom messages into Matlab (Windows) i ran into the following error:
`Error using logical
NaN values cannot be converted to logicals.

Error in ros.internal.MessageParser/getDataStructure (line 399)
feval(obj.MLTypeConverter(dataType),str2double(constantValues{i}));

Error in ros.internal.ServiceParser/getContentsOfServiceDefinition (line 161)
serviceDefinition = getDataStructure(parser,filePath,...

Error in ros.internal.ServiceParser/getServiceDefinitionHelper (line 123)
getContentsOfServiceDefinition(obj,parser,filePath,contentsOfFileForRequest,CirDependList);

Error in ros.internal.ServiceParser/getServiceDefinition (line 80)
getServiceDefinitionHelper(obj,CirDependList);

Error in ros.internal.clientserverEmitter (line 43)
[msgDefnForRequest, msgDefnForResponse] = getServiceDefinition(parser);

Error in rosgenmsg (line 348)
[genFiles, requestDependencies, responseDependencies] = ros.internal.clientserverEmitter(...`

After debugging in Matlab i found out that the srv start_remote_stream.srv is causing the trouble. When removing this srv file from the ros_custom_msgs folder and commenting out in the CMakeLists.txt i was able to rosgenmsg the zed_interface and have all the custom msgs and srvs in matlab EXCEPT start_remote_stream.srv.

Ahh also if you have trouble with rosgenmsg and MATLAB 2021b check this link:

and look for the temporary workaround ... this is important

Maybe this helps someone
