Expression.V2.Compat (expression v2.41.3)

Compatibility module to make the transition from V1 to V2 a bit easier, hopefully.

It does a few things:

  • It swaps out V2 callbacks for V1 callbacks when evaluating expressions with V1.
  • It does some patching of the context to match V1's assumptions:
    • case insensitive context keys
    • casting of integers
    • casting of datetimes
  • It compares the output of V1 to V2, if those aren't equal it will log an error and return the V1 response.
  • If there is no error it will return the value from V2.

NOTE: This module does twice the work because it runs V1 and V2 sequentially and then compares the result before returning a value.

NOTE: This was throwing more errors in prod than anticipated, hacking in a revert temporarily
