Pact test ignores the date format and fails

[timon483]

Hello,

We have an issue that after migration some Pact tests fail. It seems that the test ignores the matching rule for the date in contract.

Matching rule:
"$.entity.month": {
"matchers": [
{
"match": "date",
"format": "yyyy-MM"
}
],

Maven dependency:

    <dependency>
        <groupId>au.com.dius.pact</groupId>
        <artifactId>consumer</artifactId>
        <version>4.1.24</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>au.com.dius.pact.consumer</groupId>
        <artifactId>java8</artifactId>
        <version>4.1.24</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>au.com.dius.pact.consumer</groupId>
        <artifactId>junit5</artifactId>
        <version>4.1.24</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>au.com.dius.pact.provider</groupId>
        <artifactId>junit5</artifactId>
        <version>4.1.24</version>
        <scope>test</scope>
    </dependency>

The tested event has a field in format "yyyy-mm". However, I get the following output:

1.1) body: $.entity.month Expected "2023-02" to match a date of 'yyyy-MM-dd': Unable to parse the date: 2023-02

It seems that the field "format" of matcher is just ignored and the test expects a date in standard format.

I have tried to change the version of pact provider and consumer. But it didn't help at all. Can it be a Java version issue?

Expected behaviour: the test is green.

Environment: Java 17, Kotlin

Please tell me if you need extra information! And thank you in advance.

The issue was solved after I updated the dependency to 4.1.41
