PNP People Picker no users returned

[kboecher]

I have an PNP people Picker in a spfx web part, but It doesn't find any users

I get error 400 (Failed to load resource) on /_api/SP.UI.ApplicationPages.ClientPeoplePickerWebServiceInterface.clientPeoplePickerSearchUser 

My control

  <PeoplePicker

    context={props.context}

    titleText="People Picker"

    personSelectionLimit={3}

    //groupName={"Team Site Owners"} // Leave this blank in case you want to filter from all users

    showtooltip={true}

    required={true}

    disabled={false}

    onChange={_getPeoplePickerItems}

    showHiddenInUI={false}

    principalTypes={[PrincipalType.User]}

    resolveDelay={1000} />

I had the same issue with version 3.10.0. A downgrade to version 3.9.0 helped

npm install @pnp/spfx-controls-react@3.9.0

Yes, it works, thanx :) - do you know why?

I think the problem was that the a "GET" request to a SharePoint API was fired, but it had to be a "POST" request, but i not sure
