[BUG] Failed to decode the field

[shekohex]

I get the following error when trying the hello world blueprint.

 INFO gadget: Pre-processing event for sid/bid = 0/0 ...
 INFO gadget: Pre-processing event for sid/bid = 0/0 ...
 INFO gadget: Pre-processing event for sid/bid = 0/0 ...
 INFO gadget: Found actionable event for sid/bid = 0/0 ...
thread 'tokio-runtime-worker' panicked at src/lib.rs:17:1:
Failed to decode the field
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
ERROR gadget: An Event Handler for SayHelloEventHandler has stopped running
ERROR gadget: Job 0 exited prematurely
Error: Other("Error in Event Handler for SayHelloEventHandler: RecvError(())")

Steps

1. Create the blueprint using the blueprint template
2. Build and deploy the blueprint using tangle cli
3. Register on the blueprint using any account (ex //Bob)
4. Request an instance using another account (ex //Charlie)
5. Approve the request from Bob
6. Dispatch a job call for job#0 without any parameters using Charlie
7. you will get the above error.

Expected

When I get invalid job args, or empty, the worker should not stop and instead recover gracefully without panicking!
