testInvoke error debugging about neo-boa

[hi0001234d]

Here is another snap from old version neo-python client, if it helps

I don't think config sc-debug-notify is what you want. Try
config sc-events on for reading smart contract events in the output stream. Use
config vm-log on to log every VM op to a file ( usually vm-instructions.log or something like that in the root of the project.)

Also, you can't concat string with +. use the concat method from boa.builtins

[hi0001234d]

Okay, thanks for the instructions.

Yeah I'm not using + for string concat but not sure from where that error comes up, that's what I'm trying to figure out.

I'd tried what you said but still failed to get enough information about error to find the cause of issue. This is what error says

here is snap also

Sorry to bother you, I forgot to check log file now I checked vm_instructions.log file and I got some info but they are assembly like codes and not sure how to trace them back to my contract script.

Can you please give me idea how can I trace them back, is it possible?

see below

Your older issue here #53 talks about this, but that I think is for debugging while building contracts if I understood the code correctly here

neo-boa/boa/code/module.py

Line 570 in 06b1bfc

def export_debug(self, output_path):

.

[hi0001234d]

Now I can see more details and have access to debug.json file when I'd tried to build similar contract again. In debug.json there is no error I think its obvious because contract built successfully and had created avm file but test invoke failed and thrown a little more informative error

here is the error, let me know if you can tell what could be causing this

Closing it, finally found the issue was with one of the string operation which was not + (concat) though but something else.
