panic: invalid Go type math.LegacyDec for field cosmos.mint.v1beta1.QueryInflationResponse.inflation

[civet148]

Bug description

Hi, I just using the bdjuno (branch v0.47.x) to sync my test net in local (5 nodes 5 machines) , I added the mint module to config file, very day 12 PM, there was a panic when sync the infaltion from my node (Cosmos SDK v0.47.3) , I tried to downgrade the grpc/protobuf version, still has this problem.

above is the bug log

yes, I tried cosmos-sdk simd in command line

# It's crashed
simd query mint inflation --grpc-addr 192.168.1.26:9090 --grpc-insecure

# It's works
simd query mint inflation --node tcp://192.168.1.26:26657

Hey yes I believe this is a bug inside the cosmos-sdk and it actually occurs in several chains we support. Until this is fixed you can try to query API endpoint instead to get the latest inflation value, here is an example thanks :)
