Improve error messaging when building specs fails #475
Description
The current error message when building specs fails is unclear and does not provide enough context for debugging, we should improve this messaging to improve developer experience and troubleshooting.
How to replicate it
If I run pop build spec --chain ./wrong-chain-spec I get this error:
Error: IO error: command ["/templates_test/evm/target/release/parachain-template-node", "build-spec", "--chain", "./wrong-chain-spec", "--disable-default-bootnode"] exited with code 1
Caused by:
command ["templates_test/evm/target/release/parachain-template-node", "build-spec", "--chain", "./wrong-chain-spec", "--disable-default-bootnode"] exited with code 1
While If I run
./target/release/parachain-template-node build-spec --chain ./wrong-chain-spec
I get a more clear one:
Error: Input("Error opening spec file `./c`: No such file or directory (os error 2)")
