When running this minimal actor with n > 39
actor Test {
public query func example(n : Nat) : async Text{
var output : Text = "\n";
var current_row: Nat = 0;
for (index in Iter.range(0,n*n-1)){
if (index/n > current_row){
output #= "\n";
current_row += 1;
};
output #= "◼";
};
return output;
};
};
it will fail with the following error:
Mar 21 17:31:31.284 WARN Could not perform query on canister: IC0502: Canister ic:9888BAFBFF1508D5AC trapped: stack overflow, Application: Http Handler
Somehow it seems like a Text can’t contain more than 1634 characters?
