PasswordGrantProvider can not use

[reoxu]

we use

com.ocadotechnology
sttp-oauth2_2.12
0.15.2

got this err

How can we use PasswordGrantProvider in right way.

Hi @reoxu,

If you look at signature of PasswordGrantProvider:

def apply[F[_]: MonadThrow](
    tokenUrl: Uri,
    clientId: NonEmptyString,
    clientSecret: Secret[String]
  )(
    backend: SttpBackend[F, Any]
  ): PasswordGrantProvider[F]

You need to use an effect (F), for which you have and instance of both SttpBackend and MonadThrow, for example cats's IO. If you would share a type of your backend value I could help you more.

[bwiercinski]

it have to be one of synchronous backend, as compiler is looking for cats.MonadThrow[Identity]. imo the library should input use sttp.model.MonadError not cats' MonadThrow. i've made similar migration in ac508e4 commit

Hi @majk-p, i download v0.16.0 source and try to build it, but failed.

I fix code
mdocVariables := Map(
"VERSION" -> "0.16.0"
// "VERSION" -> { if (isSnapshot.value) previousStableVersion.value.get else version.value } )
got jar file name like this sttp-oauth2_2.12-HEAD+20230110-1326.jar

[reoxu]

I use sttp-oauth2_2.12-HEAD+20230110-1326.jar, got this err.

Maybe this pr need to test or i miss something
#336

i've made an new issue since it is not related with this one. pls use #337. in my opinion this issue is solved and we are waiting with closing until the version is properly released.
