The `dataPath` was present (but not in the type) in previous versions of
the
error library that we use. But with the recent major upgrade, it's
been removed and the `instancePath` property has finally come into use.
This PR removes all the handling for the previous property and
replaces it with `instancePath`. Because the `dataPath` used full
stops and the `instancePath` uses slashes, we need to change a little
bit of the handling too.
Switch the express-openapi implementation from our internal fork to the
upstream version. We have upstreamed our changes and a new version has
been released, so this should be the last step before we can retire our
fork.
Because some of the dependencies have been updated since our internal
fork, we also need to update some of our error handling to reflect this.
In some of the places we used `NoAccessError` for permissions, other
places we used it for a more generic 403 error with a different
message. This refactoring splits the error type into two distinct
types instead to make the error messages more consistent.
Apparently Jest doesn't like it when you use multiple stringContaining
statements for one property. Only the last `stringContaining`
statement is evaluated while the others are ignored.
This means that a lot of these assertions were never checked. To fix
that, I've extracted them into separate assertions.
This PR updates endpoints and schemas for the API tokens tag.
As part of that, they also handle oneOf openapi validation errors and improve the console output for the enforcer tests.
This PR improves our handling of internal Joi errors, to make them more
sensible to the end user. It does that by providing a better description
of the errors and by telling the user what they value they provided was.
Previous conversion:

## Restructuring
This PR moves some code out of `unleash-error.ts` and into a new file.
The purpose of this is twofold:
1. avoid circular dependencies (we need imports from both UnleashError
and BadDataError)
2. carve out a clearer separation of concerns, keeping `unleash-error` a
little more focused.
This PR adds the missing serialization of the AuthenticationRequired
response back in. It was mistakenly removed in #3633.
This PR also adds another test to verify that it the options property is
present.
This PR attempts to improve the error handling introduced in #3607.
## About the changes
## **tl;dr:**
- Make `UnleashError` constructor protected
- Make all custom errors inherit from `UnleashError`.
- Add tests to ensure that all special error cases include their
relevant data
- Remove `PasswordMismatchError` and `BadRequestError`. These don't
exist.
- Add a few new error types: `ContentTypeError`, `NotImplementedError`,
`UnauthorizedError`
- Remove the `...rest` parameter from error constructor
- Add an unexported `GenericUnleashError` class
- Move OpenAPI conversion function to `BadDataError` clas
- Remove explicit `Error.captureStackTrace`. This is done automatically.
- Extract `getPropFromString` function and add tests
### **In a more verbose fashion**
The main thing is that all our internal errors now inherit
from`UnleashError`. This allows us to simplify the `UnleashError`
constructor and error handling in general while still giving us the
extra benefits we added to that class. However, it _does_ also mean that
I've had to update **all** existing error classes.
The constructor for `UnleashError` is now protected and all places that
called that constructor directly have been updated. Because the base
error isn't available anymore, I've added three new errors to cover use
cases that we didn't already have covered: `NotImplementedError`,
`UnauthorizedError`, `ContentTypeError`. This is to stay consistent in
how we report errors to the user.
There is also an internal class, `GenericUnleashError` that inherits
from the base error. This class is only used in conversions for cases
where we don't know what the error is. It is not exported.
In making all the errors inherit, I've also removed the `...rest`
parameter from the `UnleashError` constructor. We don't need this
anymore.
Following on from the fixes with missing properties in #3638, I have
added tests for all errors that contain extra data.
Some of the error names that were originally used when creating the list
don't exist in the backend. `BadRequestError` and
`PasswordMismatchError` have been removed.
The `BadDataError` class now contains the conversion code for OpenAPI
validation errors. In doing so, I extracted and tested the
`getPropFromString` function.
### Main files
Due to the nature of the changes, there's a lot of files to look at. So
to make it easier to know where to turn your attention:
The changes in `api-error.ts` contain the main changes: protected
constructor, removal of OpenAPI conversion (moved into `BadDataError`.
`api-error.test.ts` contains tests to make sure that errors work as
expected.
Aside from `get-prop-from-string.ts` and the tests, everything else is
just the required updates to go through with the changes.
## Discussion points
I've gone for inheritance of the Error type over composition. This is in
large part because throwing actual Error instances instead of just
objects is preferable (because they collect stack traces, for instance).
However, it's quite possible that we could solve the same thing in a
more elegant fashion using composition.
## For later / suggestions for further improvements
The `api-error` files still contain a lot of code. I think it might be
beneficial to break each Error into a separate folder that includes the
error, its tests, and its schema (if required). It would help decouple
it a bit.
We don't currently expose the schema anywhere, so it's not available in
the openapi spec. We should look at exposing it too.
Finally, it would be good to go through each individual error message
and update each one to be as helpful as possible.
