[ERROR] An error occurred (InvalidIPAddress.InUse) when calling the RunInstances operation: Address XXX.XXX.XXX.XXX is in use

[juanhurtado00]

I HAVE AN AUTOMATION THROUGH LAMBDAS FOR THE CREATION OF EC2, IT IS GENERATING ME THE FOLLOWING ERROR:

[ERROR] An error occurred (InvalidIPAddress.InUse) when calling the RunInstances operation: Address 10.xxx.xxx.xxx is in use.

THE CODE IS THE FOLLOWING IN PYTON 3.9:

THE LAMBDA FUNCTION WAS WORKING WELL 2 WEEKS AGO, BUT SINCE THEN IT IS GENERATING THE ERROR WHEN IT IS RUN, IT CREATES THE EC2 WITH ALL THE ATTRIBUTES, BUT IT SEND ERROR.

PLEASE YOUR HELP VALIDATING IF THE CODE IS WRONG OR YOU HAVE TO GENERATE A CHANGE

[tim-finnigan]

As mentioned in aws/aws-cli#7176 you can refer to this EC2 documentation for the InvalidIPAddress.InUse error: https://docs.aws.amazon.com/AWSEC2/latest/APIReference/errors-overview.html

The specified IP address is already in use. If you are trying to release an address, you must first disassociate it from the instance.

Have you tried disassociating that IP address from your EC2 instance?

[juanhurtado00]

The ips do not exist, once the lambda that creates the ec2 is executed, the code begins to validate the IPs, which generates the error InvalidIPAddress.InUse, therefore I need help to validate if the code is incorrectly parameterized and at what point it is can adjust

[tim-finnigan]

@juanhurtado00 I think in this case you might be best assisted by reaching out to AWS support. They could confirm that those specific IP addresses don't exist and aren't associated with your EC2 instance.
