fix(error): adding type to error in string validator in introspect #773

santanu8961 · 2023-12-15T15:02:24Z

Closes #772

Changes

Adds type to validator error in introspect validator.

added a new optional parameter to class BaseException which can take errorType as well as errorMessage which helps to determine what kind of error is getting thrown from the validator itself. and using that to throw error in validator.
also added this in NotFoundException for better complience

Should we have a new folder for error classes and not keep it in introspect?

I think this can be named just ValidationException. If not, name of the class should be the same as the file name.

File name is stringvalidaTORexception and name of the class is StringValidaTIONException.

It should be Validator, not Validation. Internally the regex keyword is called a StringValidator.

Yes, we should ensure we can use similar approach with NumberValidator as well.

Hi @mttrbrts , @ekarademir I am keeping the name of the class as StringValidatiorException and the default error as ValidatorError and the regex error as RegexValidatorException.
let me know if this works fine . and this is what you meant.

-        throw new Error( 'Validator error for field `' + id + '`. ' + this.getFieldOrScalarDeclaration().getFullyQualifiedName() + ': ' + msg );
+    reportError(id, msg, errorType='ValidatorError') {


What is the use of this additional argument? How is it different than checking the type of the error that's been thrown?

Let's avoid having to use instanceof checks - those make assumptions about how packages are required (instanceof can fail if the same code is loaded at different version) which have bitten us in the past.

Hi @ekarademir I have used the additional argument errorType so that it can be propagated through till StringValidationException where we can use it to denote what kind of error it is , which can be very useful to do any kind of operation as only error string is quick tricky to detect what error it is trying to throw

Hi @dselman , can you please clarify what do you mean by the instance of checks?
Thanks.

I mean client code doing things like:

try { ... } catch(err) { if(err instanceof StringValidatorException) { ... } }

dselman

I like the motivation for this. I just needs a bit of refactoring to ensure it works with NumberValidator and can be cleanly consumed upstream.

I would prefer to see generic Error Code functionality moved into concerto-util/BaseException, and to refactor code to throw Errors that derive from BaseException.

Error codes should be defined constants so that code is type safe.

                this.regex = new CustomRegExp(validator.pattern, validator.flags);

I think if we want to go this route then the error codes should be defined and exported and referenced.

E.g. something like:

ErrorCodes.js export const INVALID_REGEX = 1;

Somewhere we want to report an error:

this.reportError(field.getName(), exception.message, ErrorCodes.INVALID_REGEX);

This allows a client to do something like:

import {ErrorCodes} from '@accordproject/concerto-core'; try { ... } catch(err) { const errorCode = err?.getErrorCode.?(); switch(errorCode) { case ErrorCodes.INVALID_REGEX: // do something specific here break; default: // general case }

We should have in mind that concerto-core will be moving to TypeScript and we want these error codes to be type safe.

Hi @dselman , as you requested I have changed the structure by doing the following changes to the structure:

I no longer am using the StringValidatorException class instead I have added the errorType as an optional param in BaseException and using that.

added an errorCodes.js file where I am storing the error type constants and using them directly , these are exposed so the client will also be able to use these , as discussed in the PR

This could be more generic - it extends Error and adds an Error Code. We could add an optional error code to concerto-util/BaseException, so that all exceptions can reference an error code.

Yes this is actually auto generated after I run build command
