Descrizione

Prerequisites

I have searched the existing issues
I understand that providing a SSCCE example is tremendously useful to the maintainers.
I have read the documentation
Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

What theme are you using?

core

Version

4.2.0

Current Behavior

I have a schema that makes extensive use of if/then constructs (often inside allOf blocks). Unfortunately it does not work in rjsf and throws the following error in the console:

could not merge subschemas in allOf:
Error: No resolver found for key if. You can provide a resolver for this keyword in the options, or provide a default resolver.

I have prepared a shortened example of the problematic schema: catalog.txt

Using it in https://rjsf-team.github.io/react-jsonschema-form/ reproduces the issue.

When any of the two allOf blocks is deleted, the schema starts to work just fine.

I think it might be related to #2752 .

Expected Behavior

I would like rjsf to properly render the schema.

Steps To Reproduce

Have a schema with if's inside allOf blocks at different levels in the schema
Try to render it
Observe that it doesnt work and throws an error

Environment

irrelevant (I guess)

Anything else?

No response

Guida contributor

Direzione di ricerca: The error occurs when merging allOf schemas that contain if/then blocks at different nesting levels. The console shows 'No resolver found for key if'. Investigate the schema merging logic in the utils module, likely in `src/utils.js` or similar. Look at how subschemas in allOf are merged and whether the `if` keyword is handled recursively. The issue references #2752, which may provide context. Check if the problem is in the `resolveDependencies` or `mergeAllOf` functions. The fix may require handling the `if` keyword during allOf merging or providing a resolver for it in the options.
