Error type: ArrowInvalid Details: Failed to parse string: '[254,254]' as a scalar of type int32

[pcCTC]

I am getting the following error while I am trying to upload the CSV sheet to train a model. My CSV sheet content is exactly same as shown in the example CSV file in the Auto Train page. Attaching screenshot of error for reference. I have also tried converting the index of the answer that are integer into string by placing inverted commas and also without inverted commas.
Can anyone please help me out?
FYI : I am using Chrome browser.

cc @abhishek as this seems to be related to AutoTrain.

Is there a solution for this? I’m trying to use Autotrain Question Answer as well, and my data format is:

context, answers.text, answers.answer_start, question
answer in some sentence, [answer], [0], What is the answer

The error always happens for the answer_start column, and disappears if I don’t use the list format, so in the above example it’s fine if my CSV has ..., [answer], 0, What is the answer
