@rustatian Updated, also signed my commits. And big sorry for removing template 😄

I will back to you as soon as I test whole implementation together with SDK-PHP.

[cv65kr]

@rustatian fixed and tested. I did small mistake and encoder was not needed.

@cv65kr Could you please add a PHP worker to the description (which sends this command)? I'll add it to our international tests: https://github.com/roadrunner-server/rr-e2e-tests.

[cv65kr]

@rustatian You meant workflow definition? I see general worker https://github.com/roadrunner-server/rr-e2e-tests/blob/master/php_test_files/temporal-worker.php

Also added info about definition of search attributes which need to be executed before running such test.

@rustatian to make your live easier I prepared changes in E2E repository - roadrunner-server/rr-e2e-tests#138 Feel free to modify it since I put my branches there, because we need to wait for merge.

[rustatian]
