@ANKIT GHENGE - The error you're encountering indicates a mismatch between the container IDs in the checkpoint and those in the input parameters of your dataflow. This can occur when the checkpoint is reset or if there are changes in the pipeline or activity names, which can lead to the checkpoint being invalidated.
To resolve this issue, you should ensure that the checkpoint key used in your dataflow activity is consistent with the input parameters. If you have changed the pipeline or activity names, consider using a custom checkpoint key to maintain the correct reference to the previous state of your data.
Additionally, if you are using the Change Data Capture (CDC) approach, make sure that the source data is consistent and that the checkpoint is properly configured to track changes since the last successful run.
