precompiled validator errors on anyOf

[cwendtxealth]

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, Codesandbox.io or preferably a shared playground link demonstrating the issue.

What theme are you using?

Version

5.7.0

Current Behavior

Using precompiled schema validation feature with anyOf errors when setting the anyOf field. Simple any of schema

{
  "type": "object",
  "properties": {
    "live": {
      "anyOf": [
        {
          "type": "boolean"
        },
        {
          "type": "array",
          "items": {
            "type": "string"
          }
        }
      ]
    }
  }
}

When compiled and used with precompile feature, I get this error when trying to set the field with either boolean or string array

Uncaught Error: No precompiled validator function was found for the given schema for "79bb9845"
    at AJV8PrecompiledValidator2.getValidator (precompiledValidator.ts:79:13)

Expected Behavior

Form loads and handles anyOf for precompiled schemas.

@cwendtxealth can you provide a reproducible codesandbox.io for this? Otherwise we can't figure out how to fix it.

[cwendtxealth]

@heath-freenome here is codesandbox.io for the anyOf error. If you click the live boolean or try to switch to string array and add item it crashes. From the error message it seems like the hash id generated for the compiled schema is different then the hash idea used to find the schema validator?

[cwendtxealth]

Here is an example of if/then compile errors because of subschema merge. This codesandbox tries to compile the if/then schema that is used in the playground

[cwendtxealth]

I believe I found the issue for anyOf error. In utils getClosestMatchingOption it sets a JUNK_OPTION schema as an option and passes it to getFirstMatchingOption which will then try to find that id in the compiled schema. That will throw an error because that junk schema was never in the original schema that was compiled.

I think one solution should be catching the error in AJV8PrecompiledValidator.isValid and returning false so that it doesn't crash the whole component. This is a similar approach to the base AJV8Validator.isValid.

This doesn't solve the if/then condition error for precompiled but I can open another ticket with more investigation into that. I think the anyOf can be solved with this solution.

Still experiencing this issue on 5.10.0, any hints?

[heath-freenome]

@kenvenin Are you able to provide a reproducible test case?

[kenvenin]

@heath-freenome Sorry for the late reponse, providing same sandbox but with versions changed to 5.10.0

[cwendtxealth]

@kenvenin that seems to be the old sandbox where the compile validate did not match the schema correctly. Do you have a schema sample that you are see failing? All of the complex schemas I have been using have been able to be compiled and work now. There are also a couple big fixes in 5.11.0 for compiled schema.

[kenvenin]

I apologize, my issue is probably different, I can compile the schema but when trying to import it I see the same error "Uncaught Error: No precompiled validator function was found for the given schema for...". I'm using vite so I think it's an issue with how imports from cjs are handled in my project (I can see hashed exports that start with numbers are not being imported). Would it be troubling to ask you for an example that successfully loads a precompiled schema?

[cwendtxealth]

So I ran into a similar problem because I was using the precompiled validator function dynamically without writing it to a file and could not use any tooling to transpile the javascript code. What I did is add var exports = {}; to the front of the module and export default exports; to the end of the module. In the compiled module generation it adds all of the schema functions to the exports function.

[heath-freenome]

There is also a fix coming to help deal with on-the-fly precompiled schemas
