HIVEMIND_SYNC_ARG breaks block processing if it is "" because this gets converted to a / by the cli, and cli sees "sync/" instead of "sync"

What you are describing is impossible as there are two arguments between sync and ${HIVEMIND_SYNC_ARGS:-} in the service definition: https://gitlab.syncad.com/hive/haf_api_node/-/blob/develop/hivemind.yaml?ref_type=heads#L28.

I tried to replicate this locally and as far as I can tell arguments are passed to Hivemind correctly:

[Entrypoint] 2025-01-31 10:25:05,692+00:00 INFO  [global] (main) Parameters passed directly to Hivemind docker entrypoint: sync --database-url=postgresql://hivemind@haf/haf_block_log --database-admin-url=postgresql://haf_admin@haf/haf_block_log

    raise Exception(f"unknown run mode {mode}. Accepted run modes are: `build_schema', `sync', `server', `status'")
Exception: unknown run mode sync/. Accepted run modes are: `build_schema', `sync', `server', `status'

As you can see in the logs Collected Hivemind arguments: sync, which implies the / is added later on.

I've figured it out.

Parameter substitution is made by Docker, which passes the empty parameter to Hivemind - unlike Bash, which would trim it (at least it did in my tests).

And Hivemind's entrypoint is not hardened against such an empty parameter being passed to it.

So here's a fix for Hivemind entrypoint: hivemind!844 (merged)

And for the current version of Hivemind the workaround is to set HIVEMIND_SYNC_ARGS=--community-start-block=37500000, where 37500000 is the default when no value is explicitly set: https://gitlab.syncad.com/hive/hivemind/-/blob/develop/hive/conf.py?ref_type=heads#L120
