Error While Recording A Scenario Using Gatling Performance Tool

Gatling (Open-Source)
1

Hi,

i am using gatling tool for recording for one of my application website, but on the cosole i am getting bunch of errors list displayed at the end,
Configurations i am using are:

  1. Accessing application website using vpn connection
  2. Exception Certificate is added to the firefox (Using firefox for recording)
  3. Proxy - Localhost 8000
  4. HTTPS Mode - Self Signed Certificate

11:01:25.843 [ERROR] i.g.r.h.f.SecuredNoProxyMitmActor - Connect failure with Remote(stats.manticoretechnology.com,443)
java.net.UnknownHostException: This is usually a temporary error during hostname resolution and means that the local server did not receive a response
from an authoritative server (stats.manticoretechnology.com)

11:01:26.319 [WARN ] i.n.c.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means
the last handler in the pipeline did not handle the exception.
javax.net.ssl.SSLException: Received fatal alert: bad_certificate

11:04:03.817 [WARN ] i.n.c.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means
the last handler in the pipeline did not handle the exception.
javax.crypto.AEADBadTagException: Tag mismatch!

If i continue to record script with these warnings, at the end when i open scala file then it seems that transactions are not recorded at all.

Please help me identifying whats wrong,

Thanks,

Use chrome and create http archive file (.har) file for your user events.

generate the scripts by downloading .har file in Gatling recording.

It is easy and quick way of building scripts.

Yes it is, but using recorder we get transactions separated by Tags,

So there is no other way than HAR ?

There are multiple ways where you can record or write the scripts.

Recording,HAR files and command file.

What I think, you might be missing host entries in host file.

Hi, are you talking about host entry where we put all websites in local machine ?
