Cannot disable party completely. Ask your identity manager for help

I am assembling a demo of Migrating Party to Another Participant Node but getting a runtime exception.

When I run this step in the migration process from a Canton script…

repair.party_migration.step1_hold_and_store_acs(
    alice, participant1, participant2.id, gzipfile)

… I get this error:

java.lang.Exception:
Cannot disable party alice::1220eceb59a0... completely.
Ask your identity manager for help.

Here are some more details that might be helpful:

more of the script 
participant1.parties.list().find(p => p.party.toProtoPrimitive.startsWith("alice::"))
match {
  case None => logger.error("Cannot find alice on participant1.")
  case Some(result) =>
    val alice = result.party
    logger.info("Found alice on participant1.")

    // preparation
    val mrrp = mydomain.service.get_max_rate_per_participant
    mydomain.service.set_max_rate_per_participant(0)
    participant1.domains.disconnect("mydomain")
    participant2.domains.disconnect("mydomain")
    val gzipfile = "/canton/host/configs/alice.acs.gz"

Question: What do I need to know and do to avoid this exception?

The participant must still be connected to the domain for step 1 of the migration process.

@b_heather, thank you!

Moving the disconnect(...) calls down addressed the “Cannot disable party…” error.

    // preparation
    val mrrp = mydomain.service.get_max_rate_per_participant
    mydomain.service.set_max_rate_per_participant(0)
    val gzipfile = "/canton/host/configs/alice.acs.gz"
    
    // migration
    logger.info("Beginning step one.")
    repair.party_migration.step1_hold_and_store_acs(
      alice, participant1, participant2.id, gzipfile)

    participant1.domains.disconnect("mydomain")
    participant2.domains.disconnect("mydomain")
