According to the document configuration operation, but failed
Hi @drop_dev,
"localhost" and "localhost:4100" are different things. 😉 Aren't they?
Good luck.
The "Chooser / Saver / Embedder domains" registration does not accept or require the port number, so registering just "localhost" should be correct.
@drop_dev Can you show us how you're setting up the Embedder? That is, please share the code/HTML you're using. Thanks!
