Perhaps in that URL, “rds” should not be followed by two dots. ---

I tried C1W2 lab today and did not get this error. Please let me know if you’re still encountering this issue ---

For other learners who might run into this issue: This is usually temporary. Click the Help (?) button on the upper right then click Reboot. This will reset the lab and might take a few minutes. After that, the command should now work and give you a valid endpoint. If it still fails after that, then you can report here so the staff can check. ---

Hi @chris.favila , reading your above update. I am still getting the error, after multiple reboot attempts. \*ValueError: Invalid endpoint: [https://dynamodb](https://dynamodb)..amazonaws.com \* I tried specifying a function, but I guess the lab is designed to not work this way: \*ClientError: An error occurred (UnrecognizedClientException) when calling the CreateTable operation: The security token included in the request is invalid. \* My lab ID is: pzlsvnpzasnt Would appreciate your support on this issue. Thanks in advance. ---
