pkgdown action failing at build XML

Question

✖ Failed to build XML 3.99-0.3
  
  Error: Error: <callr_remote_error: Failed to build source package 'XML'>

Has anyone else experienced this error in the pkgdown github action? Looks like a bug in building the XML package itself, not sure if there's anything I can do about it.

In the github action output looks errors like this occur. They looks specific to internal functions in XML.

OE> DocParse.c: In function ‘RS_XML_ParseTree’:
  OE> DocParse.c:165:7: error: ‘PROBLEM’ undeclared (first use in this function)
  OE>   165 |       PROBLEM "Can't find file %s", CHAR_DEREF(STRING_ELT(fileName, 0))
  OE>       |       ^~~~~~~
  OE> DocParse.c:165:7: note: each undeclared identifier is reported only once for each function it appears in
  OE> DocParse.c:165:14: error: expected ‘;’ before string constant
  OE>   165 |       PROBLEM "Can't find file %s", CHAR_DEREF(STRING_ELT(fileName, 0))
  OE>       |              ^~~~~~~~~~~~~~~~~~~~~

This issue seems to be fixed, see this issue for more details: https://github.com/r-lib/actions/issues/559 .

You can add pak-version: devel in the Github Actions. Here's an example:

- uses: r-lib/actions/setup-r-dependencies@v2
  with:
    extra-packages: any::pkgdown, local::.
    needs: website
    pak-version: devel # See https://github.com/r-lib/actions/issues/559
