# Gutenberg: error loading block

 * My block (Migrated from precursor plugin) does not render the preview in gutenberg.
   It just shows “Error loading block”.
    Block editing and frontend works.
 * This is caused by Popup Maker Plugin. The API returns
    { “code”: “rest_invalid_param”,“
   message”: “Ungültige(r) Parameter: attributes”, “data”: { “status”: 400, “params”:{“
   attributes”: “openPopupId ist keine gültige Eigenschaft des Objekts.” } } }

 * Hi [@martinder](https://wordpress.org/support/users/martinder/),
    Thanks for 
   opening this.
 * Does this same issue appear in the ‘precursor plugin,’ or only in GCB?
 * Thanks!

 * The precursor is Blocklab which auto-migrated to GCB and yes it started there.
   I hoped to fix it with the migration.

 * [@martinder](https://wordpress.org/support/users/martinder/) Could you please
   post a screenshot of your block settings, and your template code?

 * The settings and template work just fine when Popup Maker is disabled.

 * OK, thanks. It sounds like there isn’t action needed in Genesis Custom Blocks,
   right?

 * You could make it more robust if that is possible.
    I didn’t look into the details
   on what’s happening here.
 * Edit: apparently it is a gutenberg issue? See [https://wordpress.org/support/topic/popup-maker-breaks-genesis-custom-blocks-gutenberg-preview/#post-13733658](https://wordpress.org/support/topic/popup-maker-breaks-genesis-custom-blocks-gutenberg-preview/#post-13733658)
