I have tried re-installing Jmeter a multiple times now. Jmeter certificate is created and already added to Firefox

Answer 1

1. This line:

   java.lang.NoClassDefFoundError: org/apache/commons/text/RandomStringGenerator$Builder

   means that your JMeter installation is broken somehow, you're supposed to have commons-text library in JMeter Classpath

2. This line:

   2024-03-07 15:09:43,994 WARN o.a.j.p.h.p.ProxyControl: Could not read key store keystore password was incorrect;

   may mean that the auto-generated password from one of previous installations is available in Java Preferences storage so you might want to clean up this storage, storage location differs depending on the operating system you use

3. Consider upgrading to JMeter 5.6.3, you're supposed to be using the latest version of JMeter

4. There is an alternative way of recording a JMeter test: JMeter Chrome Extension, in this case you won't have to worry about proxies and certificates.
