Spot Instance Error while creating a normal instance with Boto lib

Question

I'm facing this Spot instance issue while creating an instance with the boto AWS library even if I'm not asking for a Spot instance. The issue is similar to this one : You cannot specify tags for Spot instances requests if there are no Spot instances requests being created by the request

[2022-04-19 15:39:19,236: ERROR/ForkPoolWorker-3] Task apps.broadcast.tasks.create_instance[43ea4c10-1010-47c3-9d0a-e4828fd1945c] raised unexpected: ClientError('An error occurred (InvalidParameterValue) when calling the RunInstances operation: You cannot specify tags for Spot instances requests if there are no Spot instances requests being created by the request.')

I'm using the last version of boto and here is my traceback :

    Traceback (most recent call last):

    raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (InvalidParameterValue) when calling the RunInstances operation: You cannot specify tags for Spot instances requests if there are no Spot instances requests being created by the request.

I'm simply creating an instance from a LaunchTemplate and never setting a spot instance.

Could this be related to something else?

Thanks!
