Consistent 500 on PUTs

I'm trying to create various things on dev.inrupt.net, but it fails consistently on PUT:

Error: FAILED to save new tool at: https://kjetiltest1.dev.inrupt.net/public/test2/index.ttl : Web error: 500 (Internal Server Error) on PUT of <https://kjetiltest1.dev.inrupt.net/public/test2/index.ttl>
Error: FAILED to save new tool at: https://kjetiltest1.dev.inrupt.net/public/testchat1/index.ttl : Web error: 500 (Internal Server Error) on PUT of <https://kjetiltest1.dev.inrupt.net/public/testchat1/index.ttl>
Error: FAILED to save new chat channel at: https://kjetiltest1.dev.inrupt.net/public/longchat1/index.ttl : Web error: 500 (Internal Server Error) on PUT of <https://kjetiltest1.dev.inrupt.net/public/longchat1/index.ttl>
Error: Error writing meeting configuration: Web error: 500 (Internal Server Error) on PUT of <https://kjetiltest1.dev.inrupt.net/public/testmeeting1/index.ttl>

I can't reproduce this on any of my installs.

報告只提到了對所列 dev.inrupt.net URL 的 PUT 請求，沒有提到檔案或測試。先重現一個失敗的 PUT 請求，並將其與報告者可正常運作的安裝進行比較，然後使用伺服器的錯誤輸出追蹤伺服器對 PUT 的處理。完成的標準是受影響的資源能夠成功建立且不會回傳 500 回應，並且該故障有回歸檢查。
