File Error after selecting files

Hi all,
I have been trying to select files from the file picker extension and trying to convert them to base64 using Kio4 base64 extension to upload it to drive but after selecting files i get this error

Here are my blocks:

when exactly do you get that error?

After Picking any file or image

You mean i need to set filepath instead of filename?

learn to debug your project… you might want to follow my previous advice…

i found out that when i remove the kio4 blocks there’s no error…that means there’s an error in converting files or images to base64

What eror are you getting here.

Try to debug it as @Taifun said in that thread.

As i said afterwards that when i remove the kio4 base64 blocks i don’t get that error so basically there is something wrong in converting files to base64

But what’s the error.

It’s mentioned in that post… I had attached an image

So did you tried this

yeah and as boban marked in the image i need to use fileparth and i did that too but i still get the same error

Why don’t you use cloudinary ?

Im making app for tutions classes and so they will have to upload atleast 10 -12 files per day so cloudinary storage will be not efficient

Firebase storage :sweat_smile: or it also not efficient.

Then for how many days will I be able to us it I mean estimated days the storage will get used

I don’t know about it, I just suggested you :grin:
