I'm currently facing the same issue, anyone have any idea what might the cause of the bug?

After debugging on my own, I found the problem in src/services/models/MediaType.ts on line 79:

Before this line, I already checked that this.schema and parser.spec have the correct data. However, after the creation of default, it doesn't have the correct value.

The value is processed by Sampler, which is imported from openapi-sampler.

Here’s the breakdown of what I observed:

1. Before Line 79:

• this.schema has the correct data.
• parser.spec has the correct data.

2. After Line 79:

• default does not have the correct value.

the last object of the value shouldn't be undefined, it should contains another object

It seems the issue lies within how Sampler.sample processes the schema and spec. Any insights or suggestions on how to resolve this would be appreciated.

you just need to set the value of redoc configuration generatedPayloadSamplesMaxDepth into something higher than 10
