Vercel FastAPI: Diese serverlose Funktion ist abgestürzt [geschlossen] ⇐ Python

[Anonymous]

Ich habe die FastAPI auf Vercel bereitgestellt, aber beim Erreichen des Endpunkts schlägt sie fehl
Ich habe unten vercel.json und Fehlerprotokolle eingefügt
Unten finden Sie die vercel.json-Konfiguration

Code: Select all

"version": 2,
"functions": {

[WARNING]   2025-10-22T08:53:37.387Z        LAMBDA_WARNING: Unhandled exception. The most likely cause is an issue in the function code. However, in rare cases, a Lambda runtime update can cause unexpected function behavior. For functions using managed runtimes, runtime updates can be triggered by a function change, or can be applied automatically. To determine if the runtime has been updated, check the runtime version in the INIT_START log entry. If this error correlates with a change in the runtime version, you may be able to mitigate this error by temporarily rolling back to the previous runtime version. For more information, see https://docs.aws.amazon.com/lambda/latest/dg/runtimes-update.html
