run_not_found
What happened
A run that does not exist and a run that belongs to someone else get the same answer, 404, so the reply never says whether another account's id exists.
What to do
Check the id, and that the run was started by this account.
Example
json
{
"error": {
"code": "run_not_found",
"message": "No run with this id was found.",
"detail": {
"request_id": "3c6f9a52-8e1d-4b7a-9f20-6d41a8c5e7b3"
}
}
