redis_cmd with more than two %s insertions creates parse errors

[dig12345]

Description

Add a redis_cmd() call with more than two %s insertions. Kamailio throws parse errors at startup. See below for example and log messages.

Troubleshooting

This line works fine:
redis_cmd("kam_redis", "SET %s %s-bar, "test_key", "foo" "r");

This one does not:
redis_cmd("kam_redis", "SET %s %s-%s, "test_key", "foo", "bar, "r");

Reproduction

Add a line like this:
redis_cmd("kam_redis", "SET %s %s-%s, "test_key", "foo", "bar, "r");

I have confirmed the issue with the available later version packages as well.

You have syntax errors because of missing ending " (quotes) after the 2nd and the 5th parameters. Should still be a problem, reopen with new log messages -- for me worked to pass over the syntax errors.

My bad, the example is a mistake. There is still an issue though. I will open new ticket. Thanks
