Running CodeQL within a Flask server silently interrupts connection

[cmcdougall]

I have extended the official CodeQL container to run CodeQL analysis during a Python Flask HTTP request.

Throughout the request, three codeql CLI commands are executed:

codeql database create
codeql database upgrade
codeql database analyze

create and upgrade do not interrupt the connection, but I find that when the analyze command occurs, Flask will respond as normal but the client never receives the response. Leading me to believe something within the analyze command is silently interrupting the connection.

The python code I'm using uses the Python code found in the official CodeQL Docker container. Here is the code I'm running within the request:

database_update_command = f"database upgrade {database_directory}"
database_analyze_command = f"database analyze {database_directory} --threads=0 --format=sarifv2.1.0 --output=output.json {database_lang}-security-and-quality.qls"
run_result = self.codeql.execute_codeql_command(
    database_update_command)
run_result = self.codeql.execute_codeql_command(
    database_analyze_command)

Any help would be appreciated!
