Mythx decodedLocations Error

[Miller-kk]

• MythX CLI version: v1.6.0
• Python version: v3.6
• Operating System: Ubuntu 18.04.3 LTS

Description

Below is the console in problem. When analyzing files through mythx-cli, it seems that the problem is that the json received through mythx is not properly decoded. Is it a mythx-cli problem or is it a problem with my local server?

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/mythx_models/base.py", line 85, in validate
    jsonschema.validate(candidate, cls.schema)

    raise error

During handling of the above exception, another exception occurred:

What I Did

mythx --api-key "keyValue"--format json analyze --solc-version 0.4.24 testset/itu.sol

This is a validation error in the MythX models library - a dependency of the CLI. Could you try to reinstall with pip install -U mythx-cli ? If your version didn't change, you might have to add the --force-reinstall flag. 🙂

Some background: mythx-models is a library that is concerned with parsing and serialising API requests and responses. Whenever there is a change in the API's format, validation errors can occur. I try to keep up with the changes and publish regular patch release ls for that library. These are picked up automatically with new PythX/CLI installs. Older versions might require an update.
