If you're using the REST API, you must be careful about the format you sent the body to. It should be strict JSON.
# GOOD
"{\\"scheduled_for\\":\\"2021-05-25 15:35:41 -0500\\",\\"method\\":\\"post\\",\\"headers\\":{\\"Random-Header\\":\\"Something\\"},\\"body\\":\\"Random body\\",\\"endpoint\\":\\"<https://api.fake-site.com>\\"}"
# BAD
"{:scheduled_for=>2021-05-25 15:35:41.604712 -0500, :method=>:post, :headers=>{:\\"Random-Header\\"=>\\"Something\\"}, :body=>\\"Random body\\", :endpoint=>\\"<https://api.fake-site.com>\\"}"
If the JSON can't be decoded by the Bloodbath API, it'll throw an error.
