Bug during kernel-metadata.json generation ("competition_sources")

[S1M0N38]

Bug description

I pull a Kaggle kernel to my local machine. The -m flag generate kernel metadata

kaggle kernels pull -p working -m s1m0n38/simone-bertolotto-857533

The generated kernel-metadata.json is:

{
  "id": "s1m0n38/simone-bertolotto-857533",
  "id_no": 19985783,
  "title": "Simone Bertolotto 857533",
  "code_file": "simone-bertolotto-857533.ipynb",
  "language": "python",
  "kernel_type": "notebook",
  "is_private": true,
  "enable_gpu": false,
  "enable_internet": true,
  "keywords": [],
  "dataset_sources": [],
  "kernel_sources": [
    "s1m0n38/simone-bertolotto-857533"
  ],
  "competition_sources": [
    "c/datamining2021"
  ]
}

After modify the notebook locally I try to upload it to Kaggle with

kaggle kernels push -p working

but this error message appears:
The following are not valid competition sources and could not be added to the kernel: ['c/datamining2021']

Fix

So I changed the competition_sources from "c/datamining2021" to "datamining2021" and then the upload was successful. I think that there is a bug in the kernel metadata generation process: there shouldn't be the extra "c/".

Hi @S1M0N38 - thanks for reporting this issue and associated work around. We should have a fix soon.

This should be resolved now.
