No valid Bear textbundles found in the archive. Please selec

Error message

No valid Bear textbundles found in the archive. Please select a .bear2bk backup file.

What it means

planBearBackup parsed the .bear2bk zip but none of its entries formed a valid textbundle (missing Info.json or all entries marked trashed), so the archive is not a usable Bear backup; the message tells the user to pick a proper .bear2bk file.

Solutions

1. Make sure you selected a Bear 2.x backup archive with the .bear2bk extension; older Bear 1 backups use a different format.
2. Verify the archive is not corrupted — re-export the backup from Bear and try again.
3. Check that the zip archive contains .textbundle entries at its root; nested or renamed archives will not be detected.

Example fix

// In Bear: File > Export Notes > Bear2Backup (.bear2bk)
// Then import that exact file — do not unzip and re-zip it,
// which can strip the .textbundle entries the importer looks for.
