issue with morpheusvm

[HowHsu]

github.com/ava-labs/hypersdk/compare/main...HowHsu:hypersdk:main
I'm new to learn hypersdk and I write some toy code based on morpheusvm, the function is simple, just store some data on chain. But sending the transaction to the local rpc causes the chain stall. Would be super thankful if someone can review this code.

By the way, where can I find the log file, I tried to fmt.Printf in actions's Execute function, but can't find any corresponding output under ~/.tmpnet

To re-produce this issue:

1. apply the diff to the main branch
2. in example/morpheusvm, run ./script/build.sh
3. compile morpheus-cli, and run morpheus-cli action store
4. enter the arguments, an uint and a string
5. it stalls
