Property Of Type String Or Blank In Record Schema Definition
Understanding the Challenge
When working with schema definitions in Copilot Studio, you may encounter situations where a property can have multiple data types. In this case, you're dealing with a property that can be either a string value or blank (null). This type of property is known as a union type, which is a combination of two or more data types.
Defining Union Types in Copilot Studio
To define a union type in Copilot Studio, you can use the |
operator to separate the two possible data types. For example, if you want to define a property that can be either a string or a blank value, you can use the following syntax:
{
"type": "record",
"name": "example",
"fields": [
{
"name": "property",
"type": ["string", "null"]
}
]
}
In this example, the property
field can have two possible data types: string
or null
. The null
value represents a blank or missing value.
Using the Blank
Type
In some cases, you may want to use the blank
type instead of null
to represent a blank or missing value. The blank
type is a special type in Copilot Studio that represents a value that is not present or is empty.
To use the blank
type, you can replace null
with blank
in the previous example:
{
"type": "record",
"name": "example",
"fields": [
{
"name": "property",
"type": ["string", "blank"]
}
]
}
Using the Union
Type
Another way to define a union type in Copilot Studio is to use the union
type. The union
type allows you to combine multiple data types into a single type.
To use the union
type, you can define a new type that combines the string
and blank
types:
{
"type": "record",
"name": "example",
"types": [
{
"name": "property_type",
"type": ["string", "blank"]
}
],
"fields": [
{
"name": "property",
"type": {"$ref": "#/types/property_type"}
}
]
}
In this example, the property_type
type is a union of string
and blank
types. The property
field then references the property_type
type.
Best Practices
When working with union types in Copilot Studio, it's essential to follow best practices to ensure that your schema definitions are accurate and consistent.
Here are some best practices to keep in mind:
- Use the
|
operator to separate the two possible data types in a union type. - Use the
null
orblank
type to represent a blank or missing value. - Use the
union
type to combine multiple data types into a single type. - Define a new type that combines the two possible data types in a union type.
- Reference the new type in the field definition.
Conclusion
Defining a property of type string or blank in a record schema definition can be challenging, but it's essential to understand how to work with union types in Copilot Studio. By following the best practices outlined in this article, you can create accurate and consistent schema definitions that meet your needs.
Common Use Cases
Here are some common use cases where you may need to define a property of type string or blank:
- User input: When working with user input, you may need to define a property that can be either a string value or blank (null).
- Data validation: When validating data, you may need to define a property that can be either a string value or blank (null).
- Data transformation: When transforming data, you may need to define a property that can be either a string value or blank (null).
Troubleshooting
If you're experiencing issues with defining a property of type string or blank, here are some troubleshooting tips to keep in mind:
- Check the schema definition: Make sure that the schema definition is accurate and consistent.
- Check the data type: Make sure that the data type is correct and consistent with the schema definition.
- Check the field definition: Make sure that the field definition is accurate and consistent with the schema definition.

Q: What is a union type in Copilot Studio?
A: A union type in Copilot Studio is a combination of two or more data types. It allows you to define a property that can have multiple data types.
Q: How do I define a union type in Copilot Studio?
A: To define a union type in Copilot Studio, you can use the |

Q: What is the difference between null
and blank
types in Copilot Studio?
A: In Copilot Studio, null
and blank
types are used to represent a blank or missing value. However, blank
is a special type that represents a value that is not present or is empty.
Q: How do I use the blank
type in Copilot Studio?
A: To use the blank
type in Copilot Studio, you can replace null
with blank
in the schema definition. For example:
{
"type": "record",
"name": "example",
"fields": [
{
"name": "property",
"type": ["string", "blank"]
}
