Splunk query not producing expected result

[ravimishrabglr]

Below query is producing expected result only sometime, but not working for similar data on some other random days.

Query:

index=my_summary source=app_response_status report=app_response_status ApiName=metadata
| timechart span=1d sum("200"), sum("404")

Working Data:

10/24/2021 00:00:00 +0000, search_name=app_response_status, search_now=1635123600.000, info_min_time=1635033600.000, info_max_time=1635120000.000, info_search_time=1635124485.280, 200=7552, 404=7582, ApiName=metadata, info_sid=scheduler__gmrm_VkEtdm1lLXJ0bXMtc2g__RMD50cd89fe00e4c64f8_at_1635123600_39072, RowTotals=15134, info_max_time="1635120000.000", info_min_time="1635033600.000", info_search_time="1635124485.280", report=app_response_status

Not Working Data:

09/03/2021 00:00:00 +0000, search_name=app_response_status, search_now=1630717200.000, info_min_time=1630627200.000, info_max_time=1630713600.000, info_search_time=1630717575.202, 200=9483, 404=5287, ApiName=metadata, info_sid=scheduler__gmrm_VkEtdm1lLXJ0bXMtc2g__RMD50cd89fe00e4c64f8_at_1630717200_72746, RowTotals=14770, info_max_time="1630713600.000", info_min_time="1630627200.000", info_search_time="1630717575.202", report=app_response_status 

I am not able to figure out the problem, both data looks same to me, but not sure why it is not working. pls help.

Probably depends on what parsing rules you have for this sourcetype. Try to search for the first event and do

| table *

on it. Then do the same with the other one.

I'm not sure if you're not having some extra spaces before/after commas in one of the events but I can't tell if this breaks your parsing.
