no function clause matching in Meeseeks.Accumulator.One.add/3

[fireindark707]

I'm using some xpath like "//center[h2[@class='chapter' and contains(text()[preceding-sibling::br],'some string')]]/following-sibling::h3[@class='news-title']"

And here is the error:

** (FunctionClauseError) no function clause matching in Meeseeks.Accumulator.One.add/3    

    The following arguments were given to Meeseeks.Accumulator.One.add/3:

        # 1
        %Meeseeks.Accumulator.One{
          value: #Meeseeks.Result<{ <h3 class="news-title">some string</h3> }>
        }

        # 2
        #Meeseeks.Document<{...}>

        # 3
        566

    Attempted function clauses (showing 1 out of 1):

        def add(%Meeseeks.Accumulator.One{value: nil} = acc, document, id)

I'm not sure what happened, but if I removed [@class='news-title'] at the end, meeseeks runs normally.

Can you provide an html sample that can be used to re-create the issue?

Yes, of course.

<center><h2 class="chapter">021<br>some string</h2></center>
<h3 class="news-title">some news title</h3>
