Hi @palanisamyc, welcome to the DAML forums! Your error looks like the one discussed here: I get "Trying to look up template ..." error in front end

Do the solutions there fix your problem?

That looks like a typescript error in the UI code. Is this a component you’ve written yourself, or is it an example that’s available somewhere?

This code is from the daml ui code base. Did anyone face this issue anytime before?

This looks like you might have ended up with two different versions of @types/history. Could you share your yarn.lock file (if using yarn) or package-lock.json (if using npm)?

Hi @palanisamyc, this issue was caused by using a newer version of @types/history than the one in daml-ui-templates yarn.lock file. We have updated daml-ui-template today to work against the latest version of @types/history which should resolve the issue.
