PATCH failed with "an unknown value was passed to the validate function"

[OoDeLally]

I solve this issue after 4 hours of wall-head-banging and debugging, so I'm just posting it for the next guy who gets this issue.

When trying to PATCH a simple entity, I was getting the following error:

{
  "statusCode": 400,
  "message": [
    "an unknown value was passed to the validate function"
  ],
  "error": "Bad Request"
}

without any other form of explanation.

My problem was that I set up a global ValidationPipe at the root of my Nest app:

app.useGlobalPipes(
    new ValidationPipe({
      whitelist: true,
      forbidNonWhitelisted: true,
      transform: true,
      forbidUnknownValues: true,
    }),
  );

For some reason (nest noobie here), it doesnt play well with nestjsx/crude.

After removing it, it worked fine again.

Just faced the same problem. Configuration of ValidationPipe has no effect. Solution was:

• Remove all packages, lock files, and build results. rm -rf dist node_modules package-lock.json
• Install again packages, but DO NOT USE --legacy-peer-deps flag. Only a common installation like npm i
• Fixed
