SchemaEmptyParserError: Parser Output is empty

[loukut]

Having an issue with the Parser show ap dot11 5ghz summary it provides and output of SchemaEmptyParserError: Parser Output is empty. I'm running this on the WLC 9800 controller. I think it may have an extra column at the end if I look at the source parser it doesn't seem to search for the channel column?

Hi @loukut - Thank you for reaching out. Just to confirm - This is on IOSXE. Right? Also could you please forward the exact cli command input and the output.

[loukut]
