Common Errors
Common errors and how to fix them
400: Embed inactive or inaccessible
You can activate and deactivate embeds in the praktikum.io App. If your embed is inactive, simply activate it again to resolve this issue.
403: Origin not allowed
For security reasons, embeds can only be used from allowed URLs (origins). If you see this error, please double-check that the URL of the website where you are using the embed is listed in the praktikum.io App as an allowed URL for that embed.
You can read more about how origins and allowed URLs work with stafftastic services in our origin configuration guide.
404: Embed not found
Embeds are identified by a unique ID. If you see this error, please double-check that the data-embed-id attribute in your embed snippet is correct and exists.
If you recently changed your embeds, make sure you update the snippet on your website as well.
If you deleted the embed in the praktikum.io App, you will need to create a new embed and update the snippet on your website.
Embed is displayed too small or too large
Embeds are implemented as shadow DOM elements. While they are largely unaffected by the styles of the website they are embedded in, they do inherit font sizes from their parent root elements. If your embed appears too small or too large, please check the font-size CSS property of the <html> element as our styles depend on rem units.
font-size on the <html> element, this is likely causing accessibility issues for end-users who need to change the default font size.
