Solutions

1. Import via the desktop client.
2. Remove or compress the oversized file inside the archive.

When it happens

Trigger: Thrown by preflightWebZipImport or preflightWebFilesImport when any single entry's size exceeds webImportLimits.maxEntryBytes (8 MiB).

Common situations: Occurs when one file in the import is larger than 8 MiB. Shrink or remove that file, or import in the desktop client.
