Question #: 44
Topic #: 5
A developer needs to create a process for the Human Resources team. During the development, they try to run the workflow containing the following dictionary variable:
What is the possible cause of the error?
A.
The assign's set value syntax should be PinMapping["John Doe"].
B.
The "John Doe" key was not present in the dictionary.
C.
The Dictionary was not initialized.
D.
The assign's set value syntax should be PinMapping<"John Doe">.
The most likely cause of the error is that the dictionary was not initialized. In UiPath, a dictionary must be initialized before assigning values to its keys. If you attempt to add a key-value pair to a dictionary that has not been initialized, you will encounter a runtime error.
The correct initialization can be done as follows:
PinMapping = New Dictionary(Of String, String)
Explanation of Other Options:
A. PinMapping["John Doe"]: This is the correct syntax for accessing or assigning a value to a dictionary key. There is no issue with this syntax.
B. The "John Doe" key not present: While it is true that the key might not exist, this specific error would occur only during a Get operation, not an assignment.
D. PinMapping<"John Doe">: This is incorrect syntax for working with dictionaries in UiPath.
