Hey,
Firstly, Thank You so much for this library.
I am following below DownloadOTA example and got the below mentioned error.

Here's what i did.

1. Stored firmware file in firebase cloud storage.
2. Saved the file url in RTDB variable.
3. Provided the RTDB variable path to download OTA function.

Why store firmware in the cloud storage and use the RTDB example?

Nothing is related between Firebase Storage and RTDB which RTDB is not support storing file.

The library encrypted file or firmware file as base64 string before storing it in RTDB

You must store your firmware file to RTDB using setFile.

Please read all comments in the examples and follow it.

In case you want to use storage, here are examples for Firebase Storage and Google Cloud Storage.
