A common source of ContractTrapped are Integer overflows, those can cause your contract to trap as well.

Please, check the source of this paragraph to see if it solves your issue.

I have had the issue ContractTrapped while I wanted to add values in Solidity code without SafeMath library. The solution was to ensure safety of a source code like:

function sum(uint256 a, uint256 b) internal pure returns (uint256) {
    uint256 c = a + b;
    require(c >= a);
    return c;
}

It still seems to be a timeout issue. From the source code of slack sdk for python:

class WebClient(BaseClient):
    ...
    Attributes:
        ...
        timeout (int): The maximum number of seconds the client will wait
            to connect and receive a response from Slack.
            Default is 30 seconds.

If you init a WebClient instance without the timeout parameter, the timeout parameter is 30 seconds by default.

Trying to upload a small size file, or set a longer timeout option, to test is it a real timeout issue.
