We are using neo-boa 0.2.1 in order to work around compiler issues in neo-boa 0.2.2 (see #35).

This issue might have the same root cause as #29, but I'm creating anew since it seems like this issue is manifesting itself in a much worse way, with no identified workaround as of yet.

When issuing a testinvoke, we are getting this kind of response, even though the function only ever returns either True or False:

It seems like the actual value being returned is some kind of full representation of the stack?

If we actually try to invoke it, there are a bunch of different tracebacks as a result:

Error testing contract invoke

I have an update! After many hours of testing and trying different things, I was able to come up with a couple of hacks that work around this issue. I'll post exact steps to reproduce the issue here, which will hopefully be helpful.

Here is the commit that works around the two issues we identified, with appropriate notes and comments:

NarrativeCompany/tokensale-neo-smartcontract@e50a00f

Here is the prior version that is broken:

https://github.com/NarrativeNetwork/tokensale-neo-smartcontract/tree/0b6bb33008a9222757fa398bdf52c70d7b4f5c23

Steps to reproduce the issue:

Edit original_owner in nrvtoken.py to be the script hash of the address you'll deploy from.

Compile and deploy ico_template.py.

Run the following to bootstrap the contract:

testinvoke {script_hash} deploy []

Then, just run any of the following to see the issue:

testinvoke {script_hash} transfer_team_tokens ['{addr}',1]
testinvoke {script_hash} transfer_company_tokens ['{addr}',1]
testinvoke {script_hash} mint_rewards_tokens ['{addr}',1]

You can use any address for {addr}; it's just the destination address where the tokens will be minted to.

Then, try again with the updated version:

https://github.com/NarrativeNetwork/tokensale-neo-smartcontract/tree/master

You should see that it works properly after the changes.

I'm running into this problem as well. Is the issue that a function cannot call another function?

This should be resolved in v0.3.3
