Describe the bug you're encountering

I am using Swagger-parser to bundle yaml files into a json. The json file that contains the OpenAPI definition of my API get generated correctly and I have validated it using different tools. The problem is when using swagger-ui, sometimes the schemas can not get resolved, the ref are not resolved and showing the following errors:

Could not resolve reference: Could not resolve pointer: /components/schemas/SwedishLoanRequestBody/properties/application/allOf/0 does not exist in document

I am using component that it should be possible to be reused, but swagger-ui not always render them. I have also reproduced the problem using "https://app.swaggerhub.com/" design tool.

To reproduce...

Steps to reproduce the behavior:
Using the following OpenAPI definition
Use swagger-ui-react v5.17.1 or v5.27.0

1. Load the page that shows the swagger ui
2. Drill down in Schemas SwedishCreditCardRequestBody -> application and SwedishSalesFinanceRequestBody -> application
3. If the error occurs, you will not get the properties under "application" object
4. See error: Could not resolve reference: Could not resolve pointer: /components/schemas/SwedishLoanRequestBody/properties/application/allOf/0 does not exist in document

If you don't get the error, try the steps above one more time. You might need to repeat it several times.

Expected behavior

No errors
