I wonder whether this requires a minimal sample to be fixed.
Yes, a minimal example would help because \setupmetadata works in your
previous example.
Many thanks for your reply, Wolfgang.

Now I have the minimal sample:

[...]

   \startxmlsetups xml:meta
     %\aftergrouped{\setupinteraction%
     \setupmetadata
      [author={\xmlconcat{#1}{/h2[contains(@class,'author')]}{, }}]
     %}
   \stopxmlsetups

Use \expanded.

\startxmlsetups xml:meta
\expanded{\setupmetadata[author={\xmlconcat{#1}{/h2[contains(@class,'author')]}{, }}]}
\stopxmlsetups
