What's your issue about?

CompilerPanic:unhandled exception 'str' object has no attribute 'get'

  contract "contracts/StreamManager.vy:23", line 23:0 
       22
  ---> 23 from . import Validator
  --------^
       24

How can it be fixed?

[fubuloubu]

actually I think that Validator is a json file

[charles-cooper]

need a repro -- can you post the contents of Validator.json?

compiling with -v shows the problem --

  File "/home/charles/vyper/vyper/semantics/types/module.py", line 212, in <listcomp>
    for item in [i for i in abi if i.get("type") == "function"]:
                                   ^^^^^
vyper.exceptions.CompilerPanic: unhandled exception 'str' object has no attribute 'get'

  contract "tmp/StreamManager.vy:1", line 1:0 
  ---> 1 from . import Validator
  -------^

not sure I get it lol

[charles-cooper]

yea i mean it's not very well validated, but moving the contents of the "abi" key to top level (so the top level object is a list) fixes the compilation issue

[fubuloubu]

gotcha

to note for transparency though, this works in <0.4, so there is a bit of a regression not to support optional abi top-level key

[charles-cooper]

yea, not sure where this regression happened
