Hi,
I get following Error from backend. Looks like
backend was designed to return 204 with some content..
Apigee throws following error in Trace, when
it encounter such situation
| Properties |
| error |
Received 204
Response with message body |
| type |
ErrorPoint |
| state |
REQ_SENT |
| error.class |
com.apigee.errors.http.server.BadGateway |
| Identifier |
Fault |
Is there any ways to format above error to
below as success and respond to client (Like a success not error). Finally
responded as
Response (no content) (header: Status: 204 No
Content)
Above is the way current backend respond
but Apigee returns error.
Tried following approach.
Approach 1.Used Assign message to remove the
“Accept-Encoding” and put into TargetEndpoint Request “Postflow” but this error
still occurs (As below)
<?xml version="1.0"
encoding="UTF-8" standalone="yes"?>
<AssignMessage async="false"
continueOnError="false" enabled="true"
name="Assign-Message-1">
<DisplayName>Assign
Message-1</DisplayName>
<Properties/>
<Remove>
<Headers>
<Header
name="Accept-Encoding"/>
</Headers>
</Remove>
<IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
<AssignTo createNew="false"
transport="http" type="request"/>
</AssignMessage>
Approach 2.Tried the approach of updating the
properties to below, but did not work
<HTTPTargetConnection>
<Properties><Property name="success.codes">204</Property></Properties>
<SSLInfo>
<Enabled>true</Enabled>
</SSLInfo>
<URL>https://backendurl.com</URL>
</HTTPTargetConnection>
Or below approach also does not work
<Properties><Property name="success.codes">204
No Content</Property></Properties>
3. Looks like the error object is only
accessible when proxy reaches error state, not the response object in error
state.. hence approach of accessing response object and customizing to success
(per business requirements) in this case would be ? Please comment..
AssignMessage is one approach but if I want to
use below information to success how really the Assign Message should handle
and what variable need to update or capture what kind of match ? .
To respond to client as below instead of
Apigee indicated error
Response (no content) (header: Status: 204 No
Content)
Please suggest any other approach which you
think would response with such situation
