You should put a link to the original post: https://www.b4x.com/android/forum/t...mes-into-a-b4xtable-solved.129401/post-813065

Run in debug mode and post the line where this error happens.

[Erel]

Are you using B4A 10.7 with an updated SDK: https://www.b4x.com/b4a.html ?

 

[Zkshazly]

It is already installed:

with latest version for SDK

 

[Erel]

Is this line 58?

Do While task.RunMethod("isComplete", Null) = False

 

[Zkshazly]

line 58 is as following:
ref= fs.RunMethod("getReferenceFromUrl", Array(Starter.bucket & ServerPath))

 

[Erel]

How can we know it?
It is difficult to help if you don't provide all the information.

Starter.storage is never initialized. Delete it.

Change to:

Dim fs As JavaObject = CreateFirebaseStorage

 

[Zkshazly]

Thank you very much ... now it works

and Sorry for not providing all information from the beginning
