Description
The values for file:checksum are not valid multihash values, e.g. in https://planetarycomputer.microsoft.com/api/stac/v1/collections/sentinel-3-olci-wfr-l2-netcdf/items/S3A_OL_2_WFR_20240310T021506_20240310T021806_0179_110_046_1980

Research direction
Start by opening the linked Planetary Computer STAC item and inspecting its file:checksum values against the multihash format. Trace how this item’s metadata is produced in the catalog; done means the Sentinel-3 checksums are valid multihash values and the item no longer exposes invalid metadata.
