Bicep diagnostic code - BCP048

  • Artikkel

This diagnostic occurs when a function has two or more possible signatures, but the input provided doesn't match any of them.

Description

Can't resolve function overload.

Level

Error

Solution

Ensure that the argument passed to the function matches one of the expected types defined in its overload signatures.

Examples

The following example raises the diagnostic because the length() function requires its argument to be a string, an object, or an array.

output stringLength int = length(3)

You can fix the issue by providing an argument that matches the required argument type:

output stringLength int = length('three')
