Hi @Sneha,

That looks like you are relying on the querying support for lists in the JSON API. That has been removed in SDK 1.0.0 (see https://docs.daml.com/support/release-notes.html#id17). The reason for the removal is that it didn’t turn out to be particularly useful since it only allowed for exact matches whereas you usually want a more relaxed query, e.g., that the list contains a specific element.

To recover the previous behavior, remove the list query from the API call to the JSON API and instead filter the result on the client side.
