Also errored with the same exception while using embeddable HTML scripts.

this should have been fixed by https://github.com/RocketChat/Rocket.Chat/pull/7096/files#diff-b18deaa461a67499aa1867414e83204eL13

can you please update your instance and test it? thanks

[legendecas]

@sampaiodiego I'm using latest develop Docker image. Looks like the problem still exists for every first livechat message of a guest, the second message and follows will be delivered successfully.

[sampaiodiego]

@legendecas our develop docker image is now fixed, you can pull it and test it again..

[legendecas]

@sampaiodiego yes it's fixed.
