[SOLVED] WADS - upload winpe - boot.wim failed

Good morning,
Since the version of wapt has changed from 2.60 to 2.61, I need to recreate the WinPE architecture.
However, the download of the boot.wim image stops before completion.

Code: Select all

erreur 666 Client error for url
.../../api/v3/upload_winpe?filename=Hos

I am searching in vain for the parameter to change in order to pass the limit below 360655967.
I don't see anything on the nginx side: client_max_body_size 5007520m;

watserver.log and syslog

Code: Select all

[waptserver     ] CRITICAL upload_packages failed EWaptForbiddden('Uploaded filesize 325058940 is different from the expected one 360655967')
 


Thank you in advance for your help.
Good day.

This error occurs because the WinPE image creation process uses all the PC's drivers.

For example, when using "Add Drivers from Deployment" or "Add Driver,"
both methods load all the drivers, and the sheer volume of data required to build the WinPE image is so large that it never completes.

Therefore, it's necessary to carefully refine the driver preparation by loading only the network drivers needed to initiate the initial WinPE image load.
For instance, using the following PowerShell command in administrator mode on a typical PC to retrieve only the network drivers:
`Get-WindowsDriver -Online | where { ($_.ClassName -like "Net")}`

This is what allowed me to resolve the issue.
