Disable mitm in case of an exception #47

Closed ReuDa closed 1 month ago

ReuDa commented 3 months ago

If there is an exception during setting up the rules for mitm, the mitm stays enabled blocking all traffic.

We used a wrong regular expression, for example *githubusercontent*, which leads to the following exception.

2024-07-03T12:32:54.054Z    9a9ffda4-19ee-4be3-bb8f-d0da8791da54    ERROR   Invoke Error    
{
    "errorType": "SyntaxError",
    "errorMessage": "Invalid regular expression: /*githubusercontent*/: Nothing to repeat",
    "stack": [
        "SyntaxError: Invalid regular expression: /*githubusercontent*/: Nothing to repeat",
        "    at new RegExp (<anonymous>)",
        "    at /var/task/main.js:112:27",
        "    at Array.forEach (<anonymous>)",
        "    at Runtime.handler (/var/task/main.js:111:27)",
        "    at processTicksAndRejections (node:internal/process/task_queues:96:5)"
    ]
}

The exception happens after mitm.enable() and with this PR the mitm should be disabled via the catch block.
