CLI Bug - Item edit fails from within GitHub Action

Still broken in 1Password CLI v2.31.0.

The proposed workaround doesn't work for me when attempting to edit a secure note or API credential item.

Relevant step in GitHub Actions is:

    - name: Get Tailscale auth key (Client) from 1Password
      id: get-tailscale-authkey-1password-client
      run: |
        op item get $OP_ITEM_ID --vault $OP_VAULT_ID --format json > $OP_ITEM_ID.json
        jq --arg field_id "$OP_FIELD_ID" --arg new_value "$TAILSCALE_AUTHKEY_CLIENT" '.fields |= map(if .id == $field_id then .value = $new_value else . end)' $OP_ITEM_ID.json > $OP_ITEM_ID.updated.json
      env:
        OP_ITEM_ID: 'REDACTED'
        OP_FIELD_ID: 'credential'
        TAILSCALE_AUTHKEY_CLIENT: 'clientclientclient'

    - name: Save Tailscale auth key (Client) to 1Password
      id: save-tailscale-authkey-1password-client
      run: |
        cat $OP_ITEM_ID.updated.json | op item edit $OP_ITEM_ID --vault $OP_VAULT_ID
      env:
        OP_ITEM_ID: 'REDACTED'
        OP_VAULT_ID: 'REDACTED'

Note that if I cat the updated JSON to stdout it shows that the file was correctly updated, so the issue should not be the JSON file but rather with updating the 1Password entry afterwards.

Error in the save step in GitHub Actions is:

unable to process line 1: Couldn't update the item.
