PatternMismatch

class PatternMismatch(val path: String, val raw: String, val pattern: String, val description: String? = null) : ConfigError

A string value does not match the regex declared by the @Pattern annotation.

Generated during post-deserialization validation. Like OutOfRange, the deserializer falls back to the Kotlin default when one is available.

Example:

data class Network(@Pattern(regex = "^(https?://).+") val endpoint: String = "http://localhost")

With YAML endpoint: "ftp://files":

PatternMismatch(path = "network.endpoint", raw = "ftp://files", pattern = "^(https?://).+")
