400 Bad Request response while retrieving recorded requests (java.util.concurrent.TimeoutException)

See original GitHub issue

Describe the issue When trying to retrieve recorded requests (https://www.mock-server.com/mock_server/debugging_issues.html#retrieving_recorded_requests), mock-server hangs for a moment and returns 400 Bad Request response. Internally Mock Server fails to handle the request with java.util.concurrent.TimeoutException.

What you are trying to do I am trying to retrieve recorded request to introspect the request sent by the service being tested.

MockServer version 5.11.2 (Docker image with latest label)

To Reproduce Steps to reproduce the issue:

MockServer run with Docker image
Expectation:

PUT /mockserver/expectation
{"httpRequest": {"path": "/emails/messages/"},
  "httpResponse": {"body": {"/1234/": "boo"}}
}

What error you saw

PUT /mockserver/retrieve?type=REQUESTS
{"path": "/emails/messages/"}

response:
HTTP 400 
Exception retrieving state for {\n  "method" : "PUT",\n  "path" : "/mockserver/retrieve",\n  "queryStringParameters" : {\n    "type" : [ "REQUESTS" ]\n  },\n  "headers" : {\n    "Host" : [ "myservice-mock:1080" ],\n    "User-Agent" : [ "python-requests/2.25.1" ],\n    "Accept-Encoding" : [ "gzip, deflate" ],\n    "Accept" : [ "*/*" ],\n    "Connection" : [ "keep-alive" ],\n    "Content-Length" : [ "29" ],\n    "Content-Type" : [ "application/json" ]\n  },\n  "keepAlive" : true,\n  "secure" : false,\n  "body" : {\n    "contentType" : "application/json",\n    "type" : "JSON",\n    "json" : {\n      "path" : "/emails/messages/"\n    }\n  }\n}

Expected behaviour 3. Receive recorded requests

{"path": "/emails/messages/"}

response:
HTTP 200 
[…]

Thanks, I pulled 5.13.1 this time. And it seems to fix the issue 🎉 . I have 100% success rate so far (4 runs).

22-03-24 15:44:47 5.13.1-SNAPSHOT INFO retrieved requests in json that match:

{
"path" : "/emails/messages/"
}

Thank you very much for your work and help on it!

It looks like the snapshot docker tag doesn’t contain the latest snapshot it is using 5.11.3-SNAPSHOT (as shown in your logs) but it should be 5.13.1-SNAPSHOT.

I’ve tracked down the cause and it turns out sonatype (behind maven central) has an open bug for not updating the LATEST tag for snapshots, as shown in the metadata xml downloaded from maven central snapshot repo:

<?xml version="1.0" encoding="UTF-8"?>
<metadata>
   <groupId>org.mock-server</groupId>
   <artifactId>mockserver-netty</artifactId>
   <versioning>
      <latest>5.11.3-SNAPSHOT</latest>
      <release />
      <versions>
         <version>3.7.1-SNAPSHOT</version>
         <version>3.7.2-SNAPSHOT</version>
         <version>3.8.3-SNAPSHOT</version>
         <version>3.9.18-SNAPSHOT</version>
         <version>3.9.19-SNAPSHOT</version>
         <version>3.10.9-SNAPSHOT</version>
         <version>4.1.1-SNAPSHOT</version>
         <version>5.2.4-SNAPSHOT</version>
         <version>5.3.1-SNAPSHOT</version>
         <version>5.4.2-SNAPSHOT</version>
         <version>5.5.2-SNAPSHOT</version>
         <version>5.5.5-SNAPSHOT</version>
         <version>5.6.2-SNAPSHOT</version>
         <version>5.7.3-SNAPSHOT</version>
         <version>5.8.2-SNAPSHOT</version>
         <version>5.9.1-SNAPSHOT</version>
         <version>5.10.1-SNAPSHOT</version>
         <version>5.11.3-SNAPSHOT</version>
         <version>5.12.1-SNAPSHOT</version>
         <version>5.13.1-SNAPSHOT</version>
      </versions>
      <lastUpdated>20220324065126</lastUpdated>
   </versioning>
</metadata>

I’ve committed a hack fix for this to explicitly specify the latest snapshot version.

Can you please pull the latest snapshot tag again and retry:

docker pull mockserver/mockserver:snapshot

When you run you should see each log event starts has 5.13.1-SNAPSHOT, for example:

docker run mockserver/mockserver:snapshot
2022-03-24 14:28:16 5.13.1-SNAPSHOT INFO using environment variables:

  [
  	SERVER_PORT=1080
  ]

 and system properties:

  [
  	mockserver.propertyFile=/config/mockserver.properties
  ]

 and command line options:

  [
  	
  ]
 
2022-03-24 14:28:17 5.13.1-SNAPSHOT INFO logger level is INFO, change using:
 - 'ConfigurationProperties.logLevel(String level)' in Java code,
 - '-logLevel' command line argument,
 - 'mockserver.logLevel' JVM system property or,
 - 'mockserver.logLevel' property value in 'mockserver.properties' 
2022-03-24 14:28:17 5.13.1-SNAPSHOT INFO 1080 started on port: 1080
