I’m also seeing this issue when running mmdc -i account-statement-token.mmd -o account-statement-token.png -c config.json. If I remove autonumber from account-statement-token.mmd with no other changes, the diagram is successfully generated.

account-statement-token.mmd

sequenceDiagram
  autonumber
  title: GET /account-statement-token/:accountId
  participant C as client
  participant R as router
  participant S as validation/serialization
  participant H as handler
  participant A as inner-api auth
  participant I as inner-api
  C ->> R: GET /account-statement-token/:accountId
  R ->> S: validate params
  S ->> H: params validated
  H ->> A: request auth token
  A -->> H: auth token returned
  H ->> I: request statement token
  I -->> S: statement token returned
  S -->> C: 200 - OK
  Note over S: serialize response

config.json

{
  "logLevel": 0,
  "sequence": { "actorMargin": 50, "showSequenceNumbers": true }
}

When autonumber is removed from the .mmd file, this is the output:
