Importing from a Bitwarden vault fails "No codec found"

I'm switching from Bitwarden to 1Password and after uploading my encrypted .json file to 1Password's "Import from Bitwarden" tool I get the following error after clicking next on the Upload page.

Unable to import.
no codec found to encode value in union type (Array | undefined)
Error Code:
Session: Removed in case this string is sensitive information.
Time: 2024-06-11T01:31:27.394Z

I followed instructions here and my Bitwarden account is using the proper KDF algorithm stated at the bottom of the page.

In the meantime I imported my Bitwarden vault via .csv but it does not include all the information as the .json file, such as creation date and previously used passwords.

    Please send the session ID and any other details tosupport+forum@1password.com. Be sure to use the email address tied to the account in question. Also may I ask do you have any passkeys enabled? If so please try the import with them disabled temporarily. I'm thinking that may be the issue.

    I removed the one passkey that I had but the import still fails. Unfortunately Bitwarden does not have a way to find logins with passkeys. You can export a .json file and search for "CredentialId" so I checks and can confirm that I have zero passkeys in my vault.

    Will follow up via e-mail.

    @Mendelson9 and @yossizahn

    I'm sorry for the trouble with migrating your items to 1Password. Our team just released a series of improvements to the Bitwarden importer that should avoid the issues that have been reported to us so far:

    Fix a number of bugs in the Bitwarden importer that would cause valid encrypted JSON exports to be rejected. {26893}

    Can you try importing your items again? Let me know if you still see the same issue. 🙂

    Tried importing again and got a different error.

    Unable to import.
    Unsupported Bitwarden export. Make sure that your export file is JSON encrypted with a password.

    My export file is JSON encrypted. email support said that the fix is upcoming with issue number {26890}
