GatewayTimeout 504 error on production

[ijancic]

Hello,

We are receiving the following error once in every 5 times when we try to make the GET request from Apigee to our microservices:

{"fault":{"faultstring":"Gateway Timeout","detail":{"errorcode":"messaging.adaptors.http.flow.GatewayTimeout"}}}

Do you know what is the reason for this error? When I target the prod environment with the postman directly, I don't receive this error at all.

I traced the request and pasted one part of it below:

<Point id="FlowInfo">
<DebugInfo>
<Timestamp>06-12-21 09:17:51:088</Timestamp>
<Properties>
<Property name="current.flow.name">PostFlow</Property>
</Properties>
</DebugInfo>
</Point>
<Point id="FlowInfo">
<DebugInfo>
<Timestamp>06-12-21 09:17:51:089</Timestamp>
<Properties>
<Property name="loadbalancing.targetserver">Loyalty-Data-API</Property>
<Property name="loadbalancing.isfallback">false</Property>
<Property name="loadbalancing.failedservers">[]</Property>
</Properties>
</DebugInfo>
</Point>
<Point id="Paused"/>
<Point id="FlowInfo">

<Timestamp>06-12-21 09:18:00:092</Timestamp>
<Properties>
<Property name="Identifier">fault</Property>
</Properties>
</DebugInfo>
</Point>
<Point id="Error">
<DebugInfo>
<Timestamp>06-12-21 09:18:00:092</Timestamp>
<Properties>
<Property name="error">Gateway Timeout</Property>
<Property name="type">ErrorPoint</Property>
<Property name="state">TARGET_REQ_FLOW</Property>
<Property name="error.class">com.apigee.errors.http.server.GatewayTimeout</Property>
</Properties>
</DebugInfo>
</Point>

 Can you help me with explaining how to further debug this issue on ApiGee? If you need any more data I can also add it here.

Thanks,

Ivan
