Attempt to invoke read(byte[]) on ODK Collect

My challenge has been from ODK collect. It showed an error when I was trying to get blank form which I designed. The error displayed is "attempt to invoke virtual method 'int on a null object reference".

I use ODK collect V. 1.27.3

Hi @Ollylarry
welcome to the forum! Please introduce yourself here!

Does that happen only one you download one particular form or any form from your server? If it's just one form could you attach it?

Thanks for your response @Grzesiek2010.
This happens only for this particular form.
Kindly find the attaFUNAAB_DATA.xlsx (12.7 KB) ched document

Could you tell me what language you use? I wonder if it has something to do with the error.

I use English language

I mean in the app? It's not English definitely looking at your screenshot :slight_smile: have you tried switching to English and downloading?

I use ODK Collect app and ONA as server.

Ahh it's ONA so please contact them
I have seen an error like that but can't recall now or find it. It's probably something with manifest file (not your responsibility), so you need to ask ONA.

Thank you for your response. I will contact ONA appropriately and give update as it unfolds.

Thank you @Grzesiek2010,
Haven contacted ONA, I chnaged URL of my server to
It's own working fine!

Hi fbopamu,

I guess what you wrote is in french which I do not understand but I used google to translate it.

To rectify the error, go to the server setting and change the URL to

I hope this helps.
