Bicep diagnostic code - BCP078

  • Artikkeli

This diagnostic occurs when you reference a custom-tagged union data type, but the required value isn't provided.

Description

The property <property-name> requires a value of type <type-name>, but none was supplied.

Level

Warning / Error

Examples

The following example raises the diagnostic because the property type with the value of foo or _bar_ isn't provided.

@discriminator('type')
type taggedUnion = {type: 'foo', value: int} | {type: 'bar', value: bool}

output outValue taggedUnion = {}

You can fix the diagnostic by including the properties:

@discriminator('type')
type taggedUnion = {type: 'foo', value: int} | {type: 'bar', value: bool}

output outValue taggedUnion = {type: 'foo', value: 3}

If the property value isn't provided in the preceding example, you get BCP035.
