An error containing the phrase "The target is missing" typically means that your expression is missing what?

The phrase "The target is missing" in the context of Appian expressions usually indicates that there is an expected value or reference that is absent from the expression. This often occurs when there is an issue with setting up parameters or defining locations where a value is needed.

A common reason for encountering this error is related to the syntax of the expression, specifically the need for proper punctuation to separate values clearly. In many cases, this means that a comma is required to separate multiple parameters or values being passed to a function or expression. When the expression doesn't have the correct punctuation, the system cannot identify where one value ends and another begins, leading to confusion and resulting in the error message about a missing target.

While there are other punctuation elements such as semicolons or parentheses that are also critical for syntax, they typically serve different functions; semicolons are often used for separating statements in scripting, and parentheses are necessary for overall expression grouping or function calls. Therefore, the focus on a missing comma specifically relates to how parameters and values are delineated, which aligns with the error message observed.
