Fix status code incorrect when abort() function is used

[BattlefieldDuck]

When a user calls the abort(400) function, the Flask monitoring dashboard mistakenly records a status code of 500 instead of the expected 400.

from flask import abort

@app.route('/search', methods=['GET'])
def search():
    abort(400)  # <- raise HTTPException

The underlying issue is that the HTTPException is being caught as a generic Exception, which is then incorrectly returned as a 500 error.

This pull request addresses and resolves this issue.
