When I traced a this project using strace, I got the following output.

6885  15:57:14 seccomp(SECCOMP_SET_MODE_STRICT, 0x1, NULL) = -1 EINVAL (Invalid argument)
6885  15:57:14 seccomp(SECCOMP_SET_MODE_FILTER, SECCOMP_FILTER_FLAG_TSYNC, NULL) = -1 EFAULT (Bad address)

6885  15:57:14 seccomp(SECCOMP_SET_MODE_FILTER, 0, {len=30, filter=0x55a7aaa8b490}) = 0

Seems like none of the filters are added.
I have tried it on Ubuntu 22 x86_64.
I have tried hard and any help in this regard would really be appreciated.
