Talend Cloud Databricks Error- modification_time

[TCommunity1615436108]

Hi,

I started using Talend Cloud very recently and the use case I am trying is to read data from Delta Lake using Databricks Spark Configuration. I created a Spark Batch job and used my Databricks workspace and cluster in spark configuration. When I execute the job, it is failing immediately with the following error. I tried every runtime version, but it always immediately fails. I couldn't find much conversation on "modification_time" error in Talend. Did anyone else face the same issue?
