Additional Information

OK, sorry yeah if you are able to characterize a bug like this without reference to ZJS, e.g. using bin/jerry, then it would be best to report directly on the jerryscript-debugger-ts project.

We have created a issue in jerryscript-debugger-ts/#12 for using bin/jerry to debug JS file in JerryScript. The error message is also print when connecting and debugging through Resume/Step into/Step over/Step out/Step. The different from issue #1877 is Resume/Step into/Step over/Step out/Step not disabled after one click.
