The OpenAPI generation has been significantly reforged in Ktor 3.4.0. Can you please try using the latest released version of Ktor, 3.4.2?

Sure, thanks. We will try to upgrade.

Hi @Aleksei Tirman [JB], with ktor 3.4.1 also I am getting similar errors. When I am commenting out the routes consuming self-referential models it is working.

data class QualityRuleWithLatestExecution(
val rule: QualityRule,
val execution: RuleExecution? = null,
val childRules: List<QualityRuleWithLatestExecution> = listOf(),
val executionMetrics: QualityRuleExecutionMetrics? = null
)

Could you tell me how can we include such models in openapi generation?

Thanks,
Sangeeta

Can you please try Ktor 3.4.2? If the exception is still thrown, can you please share a code snippet to reproduce the problem?

[Sangeeta]

Sure
