Possibly a stamp of entry was missing?
From the instructions for Form W-7:
"The passport isn’t a stand-alone document for certain dependents if no date of entry into the United States is present. A passport that doesn’t have a date of entry into the United States won’t be accepted as a stand-alone identification document for certain dependents."
Instructions for Form W-7 (Rev. November 2023) (irs.gov)
