First, Gatling 3.3.1 is super old, you should definitely upgrade. The latest version is 3.9.5.

Then, Gatling 3.3.1 is only compatible with Scala 2.12, not Scala 2.13. The Scala 2.13 upgrade was done in Gatling 3.5.

Note: as you’re not familiar with Scala, you should go with Gatling Java instead (only available in modern Gatling versions).

earlier error got resolved but getting a new error now
Can you please help on this
This is a built project, and it was inactive for some time so can not change the language
