! LaTeX3 Error: Unknown argument type 'k' for the command while typesetting the document. the command used is \command**{\cmd}{\oldcmd}{\lparen\rparen}

The definition is

\NewDocumentCommand{\NewMathFun}{ssmmm}{%
  \IfBooleanTF{#2}{%
    \expandafter\let\csname OP\CsToStr{#3}\endcsname#4%
  }{%
    \IfBooleanTF{#1}{%
      \expandafter\DeclareMathOperator\expandafter*\csname OP\CsToStr{#3}\endcsname{#4}%
    }{%
      \expandafter\DeclareMathOperator\csname OP\CsToStr{#3}\endcsname{#4}%
    }%
  }
  \NewDocumentCommand{#3}{ s k_ k^ k@ > {\SplitArgument{1}{}} D<>{#5} o}{%
    \csname OP\CsToStr{#3}\endcsname\IfNoValueF{##2}{_{##2}}\IfNoValueF{##3}{^{##3}}%
    \IfNoValueTF{##6}%

For some time xparse provided an experimental k argument type, then superseded by the e argument type. Please, show the faulty definition and we can help in fixing it. – egreg Sep 19 '19 at 16:38
Thanks. I am adding the definition below: – Senthil Sep 19 '19 at 16:50

is that a definition that you just wrote (in which case you are using old documentation) or is it in a package from ctan (in which case it needs updating) ? – David Carlisle Sep 19 '19 at 19:19
It's quite hard to understand what \NewMathFun is supposed to do. – egreg Sep 19 '19 at 19:56

The details on the switch from k to e type arguments is discussed in Xparse's new e-type argument (replacement for k-type argument). – Peter Grill Sep 19 '19 at 19:57
@DavidCarlisle its part of the article submitted for typesetting, having trouble in processing the same. – Senthil Sep 20 '19 at 03:44
@egreg Same here – Senthil Sep 20 '19 at 03:45
@PeterGrill Thanks will have alook at it – Senthil Sep 20 '19 at 03:45
Thanks @Marijn for editing the code – Senthil Sep 20 '19 at 03:49
Thanks @PeterGrill I was able to successfully compile the document by merely changing all k's to e's. It just dawned on me that I am outdated in LaTeX. Going thru expl3, interface3, xparse, xstring, etc. Thank you all for your time. – Senthil Sep 20 '19 at 12:47
@Senthil Is your problem solved? Can we close this question? – siracusa Sep 27 '19 at 07:53

@siracusa Yes, the problem is resolved. The question can be closed. The resolution was done by replacing all "k" with an "e" argument type. – Senthil Sep 28 '19 at 15:40

I'm voting to close this question as off-topic because it was solved in the comments – siracusa Sep 29 '19 at 00:28
