Inconsistent fields in error responses

[matthiasschaub]

Bug Description

Different error have different response structures (JSON fields).

General Information

curl -X GET "https://api.ohsome.org/v1/elements/lengh?bboxes=8.67%2C49.39%2C8.71%2C49.42&filter=waterway%20in%20(river%2C%20canal%2C%20stream%2C%20drain%2C%20ditch)%20and%20geometry%3Alie&format=json&time=2014-01-01%2F2017-01-01%2FP1Y" -H  "accept: application/json"
{
  "timestamp" : "2022-12-14T11:54:25.412+00:00",
  "status" : 404,
  "error" : "Not Found",
  "path" : "/elements/lengh"
}

  "status" : 400,
  "message" : "Invalid filter syntax. Please look at the additional info and examples about the filter parameter at https://docs.ohsome.org/ohsome-api. Detailed error message: line 1, column 67: whitespaces, EQUALS (=), NOT_EQUALS (!=) or in expected, EOF encountered.",
  "requestUrl" : "https://api.ohsome.org/v1/elements/length?bboxes=8.67%2C49.39%2C8.71%2C49.42&filter=waterway%20in%20(river%2C%20canal%2C%20stream%2C%20drain%2C%20ditch)%20and%20geometry%3Alien&format=json&time=2014-01-01%2F2017-01-01%2FP1Y"

Expected Behaviour

Both responses should contain the same fields (i.e. both should have the "message" field or "error" field)
