Error in python-example-logs-api-extension: Unexpected JSON Parsing Issue

Hi team, I am encountering below output during subsequent calls to my lambda function. The output from the console is:
```
Test Event Name
TestEvent

Response
Calling the invoke API action failed with this message: Unexpected non-whitespace character after JSON at position 7 (line 1 column 8)

Function Logs

Request ID

```
I have followed the instructions in that directory and using the layer published following them.
Tried on runtimes: Python 3.10, Python 3.9
The invocation does not fail for the first time i.e invocation after shutdown event but fails for the subsequent invoke calls.

Thanks
