Solutions

1. Use the desktop client for large document counts.
2. Split the archive into multiple smaller imports.

When it happens

Trigger: Thrown by preflightWebZipImport or preflightWebFilesImport when the number of importable documents (.md/.html/.htm) exceeds webImportLimits.maxDocumentCount (250).

Common situations: Hit when importing more than 250 Markdown/HTML documents at once in the web app. Import in smaller batches or use the desktop client.
