Hi Katarzyna

Thanks for posting in the Lucidchart Community!

I'm sorry to read that you're experiencing issues while trying to embed a Lucid diagram on your Stoplight document. 

To anyone interested in knowing how embedding works please refer to the following help documentation: Embed your document

There are a couple of specific things worth noting when working with embedding:

• Please test the embedded diagram in a Chrome Incognito browsing session. This often improves performance by clearing your cache and cookies and disabling your extensions.


• Please also try connecting to a different internet connection to make sure that there is no network interference.

If the issue persists would you please send the following information?

• In the share dialog does the Preview button successfully bring up a preview or does the same error occur?


• A screenshot of the issue/error message you are receiving


• A screenshot of the associated Javascript Console output after reproducing the issue

Thank you and thanks for your patience!
