1.x.x to 2.x.x migration type issue

[vbodnia]

Env: Node 14.15.4
Typescript 4.1.3

Currently, I am using passport-saml@1.5.0 with @types/passport-saml@1.1.2. After updating to 2.0.5 I've got a type error in MultiSamlStrategy saying:

TS2345: Argument of type 'MultiSamlStrategy' is not assignable to parameter of type 'Strategy'. Types of property 'authenticate' are incompatible. Type '(req: RequestWithUser, options: AuthenticateOptions & AuthorizeOptions) => void' is not assignable to type '(this: StrategyCreated<Strategy, Strategy & StrategyCreatedStatic>, req: Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>, options?: any) => any'. Types of parameters 'req' and 'req' are incompatible. Property 'samlLogoutRequest' is missing in type 'Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>' but required in type 'RequestWithUser'.

The problem is that I'm also extending express requests with custom fields, e.g. user.

The latest build of passport-saml includes its own types and doesn't need anything from DefinitelyTyped.

@cjbarth In fact, the same issue happens without @types/passport-saml package. I have reinstalled modules with the version 2.0.5 and got the same error.

I confirm what @vbodnia says, please reopen this issue, it's a current bug in v2.0.5.

[cjbarth]

Is this a bug at the HEAD of master?

[vbodnia]

@cjbarth Yes it is:

[cjbarth]

It seems this might be related to #549. Would you agree?

In any case, I can't see from your screen shot exactly what the problem is. Do you have some sample code I can load up?

[fluggo]

The screen shot doesn't show it, but the original description is very similar to mine. I haven't gone back with tweezers yet to figure out where mine went wrong.

@cjbarth

1. Version 2.0.5 and 2.1.0, definitely typed pkg removed. Gives the error of incompatible req type because we are extending express request with custom fields, as well as it is done in the passport-saml.
   Please see screenshots below:

2. I have tried to install pkg from master branch, but the error still persists.

[Mikescops]

I think the fix #554 by @forty solves this issue but it should be backported to 2.x

[cjbarth]

v3 of passport-saml has been released. If there is a PR to backport #554 to 2.x, we'll look at it there.
