The error you are encountering is due to an invalid parameter type for the eventValue in your code. The eventValue parameter should be of type str, but it appears to be a dictionary ({'eventValue': '0.50'}).

To resolve this issue, you can convert the eventValue parameter to a string before passing it to the put_event function. You can do this by modifying the properties dictionary like this:

'properties': {
    'eventValue': str(eventValue)
}

This will ensure that the eventValue parameter is passed as a string and resolve the parameter validation error
