@adarshks In new Reëls platform, there is no need to create constants at runtime.For constants, you should provide a static value, similar to defining a variable with an associated value. If you want to use a constant within a rule, you should declare it in the format {keyname}. Similarly, if you need to reference an input key within a rule, it should be declared as {IP_keyname}, and for an output key, it should be formatted as {OP_keyname}.
