Hello,
I have a problem to upload a form, an error message will displayed.

I use the printerwidget to create a pdf of the form include pictures, and attach at the end of the form the pdf document to sent it.
In this form are many pictures, reduced to 3072 px, but size of pdf document is 116MB.

So my question is, can anyone tell me, what the problem is?
Is there a size limit to upload forms in collect, central or my server config? Could it be changed?

At the moment it is not possible to open the form again and remove the attachment, as it has already been completed for sending.
Thanks

Hi @Maggi

Central has a default limit of 100 MB, which can be changed https://docs.getodk.org/central-troubleshooting/#file-upload-fails-with-413

Hi. I’ve tried the solution but it has not worked. Please check my post here: File too large (> 100MB) and Request Entity Too Large (413)
