I was searching for most prommising Layer 2 Project came accross Manta. Read there goal and tought why not add a spec for the lava community. Hereby you can see my spec;

> <https://github.com/BabyScope/lavaspecs/blob/main/cookbook/specs/spec_add_manta.json>

however when i try to run it in my test i got this  
Apr 6 21:59:00 ERR Failed Querying spec for chain error=“rpc error: code = InvalidArgument desc = rpc error: code = InvalidArgument desc = not found: invalid request” ChainID=MANTAT  
Apr 6 21:59:00 ERR Failed Querying spec for chain error=“rpc error: code = InvalidArgument desc = rpc error: code = InvalidArgument desc = not found: invalid request” ChainID=MANTA  
What am I doing wrong in the testscript?
