What error message indicates a missing parameter in a function call?

A syntax error typically indicates that there is something wrong with the structure of your code or expression, which could be due to missing parameters in a function call. In programming and in the context of expressions, this type of error surfaces when the syntax rules are not followed, which includes scenarios where required inputs or parameters to functions are not provided.

When a function expects a certain set of parameters and one or more of them is absent, that results in a violation of the syntactic rules governing the expression. This absence disrupts the expected format and results in an error that points to the syntax as being incorrect.

The other messages provide different meanings: "Expression evaluation error" typically suggests that the expression was structured properly but encountered an issue during execution, such as dealing with invalid data. "Target is missing" usually relates to issues where a specific target, like a field or reference, cannot be found, and "Database not found" indicates that a data connection issue has occurred, rather than an issue with the syntax of a function call.

Thus, identifying a syntax error is crucial in troubleshooting functions, as it specifically points to structural issues like missing parameters.
