Query gives error: Value cannot be null

[Arendp]

I have this query:

let
    Bron = Oauth2_18Jan.Contents("https://start.exactonline.nl/api/v1/division/cashflow/Banks"),
    #"XML-bestand geïmporteerd" = Xml.Tables(Bron,null,65001)
in
    #"XML-bestand geïmporteerd"

When loading or refreshing, it gives me this error:

Waarde kan niet null zijn. Parameternaam: accessToken  -> meaning value cannot be null. Parameter name: accessToken

Microsoft.Mashup.Evaluator.Interface.ErrorException: Waarde kan niet null zijn.

Microsoft.Mashup.Engine1.Runtime.Extensibility.ExtensionOAuthFactory.Provider.Microsoft.Mashup.OAuth.IOAuthProvider.Refresh(TokenCredential credential)
bij Microsoft.Mashup.Host.Document.OAuth.OAuthRegistrationService.Refresh(IResource resource, CredentialDataCollection previousCredential)

And the error goes on with this kind of message..

Any help on this?

Let me know if you need more info.

Hi @Arendp  , 

the function you're using isn't a native M-function. So it might come from a custom connector. You have to contact the person that has created that connector and investigate whats wrong with the authentication.
