Only the type option allows a wildcard, as the documentation details:
type string * (all), break, image, list, paragraph, run, section, style, table, table-row, table-cell.
The attributes option needs a specific key and value:
attributes array Contains a specific attribute key and value.
Sorry but as explained in our previous reply, footnotes aren't supported yet as target with customizeWordContents. These are the supported targets:
target string document (default), style, lastSection, header, footer
Supporting other targets such as footnotes and comments with customizeWordContents are a work in progress that isn't yet ready to be used in production servers.
