Display detailed messages when validation fails

[AM1988]

Hi there.

I have a class for data validation
`export class SchemaValidator {
static ajv = new Ajv({ allErrors: true, verbose: true });

public static validate<T>(schema: SchemaFile, data: T): boolean {
    const schemaContent = JSON.parse(fs.readFileSync(path.join(__dirname, 'path', schema), 'utf-8'));
    if (!this.ajv.validateSchema(schemaContent)) {
        console.error(`Schema is not valid.`);
    }
    const isValid = this.ajv.validate(schemaContent, data);

    if (!isValid) {
        const errorMessages = this.ajv.errorsText();
        logger.error(`Validation failed : ${errorMessages}`);
        return false;
    }
    return true;
}

}`
I use JSON schema described in a separate file.
How to get the full output when validation fails so that I can understand which part exactly does not match?

For example, values in the enum did not match, or input data had some additional properties, missing properties, etc.

Right now I see only data.payload.something should be equal to one of the allowed values
