It returns an unspecific error response:\n\"`Your file was not imported. Please try importing this file again.`\"\n\n\n##\n\n## Simulation\n\n\n\n1. Go to the new collections module\n2. Select the tab \"Import\"\n3. Use a sheet that has over 1000 SKUs (i.e. 300 products with 50 SKUs, each)\n4. The import will generate a timeout.\n\n\n##\n\n## Workaround\n\n\nUpload gradually using smaller sheets, the legacy CMS collections and/or the insert SKU to subcollection API https://developers.vtex.com/docs/api-reference/catalog-api#post-/api/catalog/pvt/subcollection/-subCollectionId-/stockkeepingunit"}
