Hi! I was trying to change the owner of a post via the API and managed to trigger a 500 Internal Server Error. I followed Reverse engineer the Discourse API to get the right endpoint and replicated it with the right parameters but I only got HTTP 500.
Topic ID is 159 and Post ID is 196 according to /t/159.json, so I sent the following POST request to /t/159/change-owner.json:
# library is aiohttp, language is Python
session = aiohttp.ClientSession("http://dspacl.itslemonchan.com", headers={
"Api-Key": "REDACTED",
"Api-Username": "system",
"User-Agent": "lemon/0.1"
})
data = {
"post_ids": [
196
],
"username": "lemon"
}
async with session.post("/t/159/change-owner.json", data=data) as resp:
txt = await resp.text() # so i could check if there was a message but nothing
resp.raise_for_status()
This throws an Internal Server Error and nothing happens. After checking the logs, I get the following:
