It would be useful to be able to natively evaluate whether an output variable using json.select has found a successful match/result.

Use case: an API step receives a httpResponseBody, with an output variable based on a key:value from a json.select statement.

Example output variable: <+json.select("workspaces[?(@.data.displayName == '<+pipeline.variables.accountDisplayName>')].data.id",httpResponseBody)>

We want to have a subsequent step with a conditional execution based on whether the json.select statement finds a value. In cases where the json.select does not find a match, the output variable is:

<+json.select("workspaces[?(@.data.displayName == 'example_name')].data.id",httpResponseBody)>

Since this is not a null value, we're unable to use isUnresolved expressions in subsequent conditional execution expressions. Therefore we'd like to be able to assess whether the output variable resolved to a match or not.

At the moment we are using an intermediary script step to evaluate the variable, but this is an inelegant workaround.
