Transform dates Error: The conditional operation failed

Question

The Data Flow Task seems to fail at the Transform dates task with the below error message.

[Transform dates [385]] Error: The conditional operation failed.
[Transform dates [385]] Error: SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "Transform dates" failed because error code 0xC0049063 occurred, and the error row disposition on "Transform dates.Outputs[Derived Column Output].Columns[DerivedCallStartTest]" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure.

[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PROCESSINPUTFAILED.  The ProcessInput method on component "Transform dates" (385) failed

with error code 0xC0209029 while processing input "Derived Column Input" (386). The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure.

The Transform dates is a DerivedColumn task which has the below code to create two new columns.

(CallStart == "BLANK") ? NULL(DT_DBTIMESTAMP) : (DT_DBTIMESTAMP)CallStart
(Callend == "BLANK") ? NULL(DT_DBTIMESTAMP) : (DT_DBTIMESTAMP)Callend

I also enabled the dataviewer to check what data was being passed to the task image attached for reference.

Am I missing something or what could be the reason for failure, any help or lead would be great.

Made use of a FileConnection Manager and created a new file with the contents of the input file and skipped the Trailer record from being copied over to this file. Finally started reading through the newly created file and was able to pass the task successfully.
