Send string arrays through Rpc? (Netcode for gameobject)

When trying to send an int through Rpc it works, but when sending an array unity throws a compilation error:
Assets\rpc.cs(69,50): error - Don’t know how to serialize String - implement INetworkSerializable or add an extension method for FastBufferWriter.WriteValueSafe to define serialization.

how can i fix this?
i did add [serializeField] before declaring the string.

this relates to “immutable folders” Problem. to solve this one we need to solve the other problem, and than we get a new library which inclueds “NetworkArrays” (like network variables but just for arrays).

Use it instead of sending through rpcs.
