Unable to run script in Canton ledger

Hi,

I am trying to run a Daml script in my canton ledger and I am getting this following error. The same script works fine with other kind of ledger. Any idea?

My script tries to create 2 parties and 2 smart contracts no more… :slightly_frowning_face:

Regards,
Pierre

Welcome to the forum @pierre.filliolaud, preconditions often refer to some property that is being enforced using the ensure keyword. Do you have any ensure assertions that are not being met on the Roles.PlatformAdminRole template?

If that doesn’t resolve the issue please provide a code sample that demonstrates the issue and we can help further.
