ML.net Modelbuilder for object detection

Question

I am attempting to build a model using my own data with modelbuilder to detect specific objects in images. I get to the training step and get an exception. I am using VOTT JSON data. I have tried several times but continue to get this same error.

Error description : Unable to split the file provided into multiple, consistent columns. Readable formats include delimited files such as CSV/TSV. Check for a consistent number of columns and proper escaping and quoting.

Exception:
