Error message

This import contains a nested zip. Please import it in the desktop client.

What it means

WebImportLimitError thrown in preflightWebZipImport when an entry is a .zip and nested zips are disallowed (maxNestedZipDepth 0). The web importer cannot recurse into nested archives; desktop is required.

Solutions

1. Extract the nested zip first, then import the inner archive.
2. Use the desktop client which supports nested archives.

When it happens

Trigger: Thrown by preflightWebZipImport or preflightWebFilesImport when an entry name ends with .zip while maxNestedZipDepth is 0, i.e. a zip inside the import is not allowed on web.

Common situations: Happens when the import bundle itself contains zip files. Extract them first or import the bundle in the desktop client.
