it is called from a handler with this code:

B4X:

Sub Handle(req As ServletRequest, resp As ServletResponse)
    If req.Method <> "POST" Then
        resp.SendError(500, "Method not supported!")
        Return
    End If
       
    Private StreamReader As TextReader
    StreamReader.Initialize(req.InputStream)
    Private parser As JSONParser
    parser.Initialize(StreamReader.ReadAll)
    Private m As Map = parser.NextObject
   
    If m.Get("typeNotification") = "" Then
        resp.SendError(500,"Missing parameter!")
        Return
    End If
   
    CallSubDelayed2(Main,"sendNotification",m)

End Sub

and the main code is this:

B4X:

Sub sendNotification(dataMap As Map)
   
    Token = GetTokenValue(ServiceAccountFilePath)
   
    Dim Job As HttpJob
    Job.Initialize("", Me)
    Dim data As Map = CreateMap("title": dataMap.Get("title"), "body": dataMap.Get("text"), "userSent": dataMap.Get("userSent"), _
    "userTo": dataMap.Get("userTo"),"typeNotification": dataMap.Get("typeNotification"),"selectedIdWorkout" : dataMap.Get("selectedIdWorkout"))
    Dim message As Map = CreateMap("topic": dataMap.Get("userTo"), "data": data)
    If dataMap.Get("userTo").As(String).StartsWith("ios_") Then
        'B4i
        Dim Badge As Int = 0
        Dim iosalert As Map =  CreateMap("title": dataMap.Get("title"), "body": dataMap.Get("text"))
        message.Put("notification", iosalert)
        message.Put("apns", CreateMap("headers": _
            CreateMap("apns-priority": "10"), _
            "payload": CreateMap("aps": CreateMap("sound":"default", "badge": Badge))))
    Else
        'B4A
        message.Put("android", CreateMap("priority": "high"))
    End If
    Dim jg As JSONGenerator
    jg.Initialize(CreateMap("message": message))
    Log(jg.ToPrettyString(4))
    Job.PostString($"https://fcm.googleapis.com/v1/projects/${ProjectId}/messages:send"$, jg.ToString)
    Job.GetRequest.SetContentType("application/json;charset=UTF-8")
    Job.GetRequest.SetHeader("Authorization", "Bearer " & Token)
    Wait For (Job) JobDone(Job As HttpJob)
    If Job.Success Then
        Log(Job.GetString)
    End If
    Job.Release  
End Sub

Private Sub GetTokenValue (FilePath As String) As String
    Dim GoogleCredentials As JavaObject
    GoogleCredentials.InitializeStatic("com.google.auth.oauth2.GoogleCredentials")
    Dim Credentials As JavaObject = GoogleCredentials.RunMethodJO("fromStream", Array(File.OpenInput(FilePath, ""))) _
        .RunMethod("createScoped", Array(Array As String("https://www.googleapis.com/auth/firebase.messaging")))
    Credentials.RunMethod("refreshIfExpired", Null)
    Return Credentials.RunMethodJO("getAccessToken", Null).RunMethod("getTokenValue", Null)
End Sub

additional jars used:

libraries used:

EDIT:
Removed this #AdditionalJar: firebase-server-sdk.jar and error gone! Conflict?

Can you reproduce it in a small server project?
