You should also remove the changes to cmd/juno, and the juno/*.sst files.

After that run make format, make lint, and fix any lint errors.

Finally, just make sure the tests pass on the workflows (you may need to ping someone from the juno team to run the workflows)

Hi.. I'm getting this error

on running the tests. Can anyone help?

I think I am getting error here..

func (h *Handler) JunoGetNodesFromRoot(key felt.Felt) (string, *jsonrpc.Error) {
	stateReader, _, error := h.bcReader.HeadState()
	if error != nil {
		return "", ErrBlockNotFound
	}
@>	try, _, errTry := stateReader.NodeFromRoot()
@>	if errTry != nil {
@>		return "", ErrBlockNotFound
@>	}

	k := try.FeltToKeyConverter(&key)
	storageNodes, err := try.GetNodesFromRoot(&k)
	if err != nil {
		return "", ErrBlockNotFound
	}

	parsedNodes := try.NodeParser(storageNodes)

	jsonBytes, err := json.Marshal(parsedNodes)
	if err != nil {
		return "", ErrParsingError
	}
	return string(jsonBytes), nil
}

Hi @rianhughes Please have a look at task 5

[PsychoPunkSage]

Hi @rianhughes I tried to implement NodesFromRoot Mock... but I'm facing little difficulty in doing so... Can you please have a look at the code and tell me what I'm doing Wrong?? Or what changes I have to make??

I also want to ask one more thing... I have to also do exercise 6?? Or after completing 5 I can do some contribution to juno??
