I need to remove a field data before the data gets indexed to Splunk.
The field that needs to be removed is in between the log and it has several lines.
dv_u_business_duration_in_seconds="",closed_by="",sys_created_by="",sys_domain_path="/",dv_business_duration="",dv_work_notes="2018-08-05 09:46:09 - *******
active="true",dv_made_sla="true",additional_assignee_list="",delivery_task="" field name in work_Notes
Note: I tried the null
[sourcetype:test_task] TRANSFORMS-null= tasknull
[tasknull] FIELDS = work_Notes DEST_KEY = queue FORMAT = nullQueue
Thanks in advance.

These name value pairs are extracted at search time, not index time.
props.conf might have been -
[<sourcetype name>] TRANSFORMS = tasknull
Suppressing the name value pairs extraction at search time can be done via the explanations at Disable Automatic Field Extraction or How to avoid extracting fields from quoted values?
Unfortunately, it requires disabling the extractions by
props.conf in the search heads and creating your own extractions.
You can replace the other portion of the events with blank during index time, so only the necessary information gets logged.
