Help required with the plugin and BlazeMeter - okHttp conflict error

[roddasrinivas]

I need help with below error. Issue is occurring when I am trying to to execute the test in BlazeMeter. Error is occurring only when JSR223 is used for scripting. Without JSR223, it is successfully writing data to influx dB.

Version:
JMeter 5.5
Java 11

Possible root cause is conflicting okHttp versions:

Hi @roddasrinivas, wow will take a look. Have you reproduced this on the local PC?

BR,

Hello Mike,

Problem is on Blazemeter only. In Blazemeter also, problem come only if we use JSR223 in JMeter. On local PC it is working fine. Is it possible to change okHttp jar version on plug-in? so there won't be any conflict between okHttp versions.

Best Regards,
Srinivas

The problem - I do not see any issues on local PC, or any warnings with that. We have okHttp as part of the 'influxdb-client-java' used to push data to InfluxDB. Its Java world :)))

As you can see we have no okHttp as part of dependencies.

On some installations, we had a problem like you posted #16 (the solution was described in the ticket).

I'm happy to help but I got stuck with that, I have no env. to reproduce this.

BR,
Mike
