Azure AutoML error : A field of the entity is over the size limit

Hi,
I am trying to run an automl code on Azure using the azureml SDK (class AutoMLStep). But it is throwing an error saying

`A field of the entity is over the size limit. FieldName=RunDto.Properties.Value/Length, Limit=550000, Size=697351`

` ERROR - AutoML driver_wrapper script terminated with an exception of type: `

`ExceptionTarget: Unspecified 2021-10-05 05:00:02.236 - WARNING - An service error was raised with an HTTP code 400. Error details unavailable. 2021-10-05 05:00:02.236 - WARNING - Encountered an exception of type: , interpreted as error code Service. 2021-10-05 05:00:02.544 - WARNING - An service error was raised with an HTTP code 400. Error details unavailable. 2021-10-05 05:00:02.545 - WARNING - Encountered an exception of type: , interpreted as error code SystemError.ClientError.AutoMLInternal.Service.`

How do I debug this error, to find where is this error exactly pointing to?
The version of autoML I am using is 1.34.0..
