New Relixir fails when running under an additional named supervisor

[eldano]

Steps to reproduce:

• Deploy this commit that uses a named supervisor: https://github.com/TheRealReal/api/commit/5f9e2b8c50403b95b307bfd8a06ba9b5c6641943

• Run the admin graphql healthcheck.

Expected outcome: The health check executes correctly

Actual: It fails with the following stacktrace:

[error] Task #PID<0.968.0> started from #PID<0.965.0> terminating
