Hello Jonas,

Glad to see you back at Xeek.

Please check the data tab for this challenge (here) and download the submission sample to check if there is a subtle difference with your submission.

If that doesn’t work, please use the Support button at the top of Xeek, and we can check file formats.

Hi Xeek Team,

I ran my model and I produced the output in json format. I am getting this error saying “list indices must be integers or slices, not str”.

Can you please let me know on why I am getting this error. Also to re-check or test this I submitted the sample submission file you shared in json format. I get the same error as above.

I am not sure how others were able to submit - can you please throw some inputs on submitting here!
