BUILD: ERROR: Cannot read the array length because " " is null

Since yesterday I get the message "BUILD: ERROR: Cannot read the array length because "<local3>" is null" in the console of Eclipse. It happens with any datafield that I try.

It is with SDK 3.2.5 and 4.0.1. My suspicion is that my Eclipse setup is the problem. I can build the same datafields on a different PC just fine.

I can't find a other report on this. Probably just a question of removing Eclipse?

I have removed Eclipse and installed again, but the problem persists. Is there an option to debug this? I have no variable called local3

Is is a message while running your app? Sounds like it. Maybe add a null check where you use size()?

if(myvar!=null && myvar.size()>3) {

}

Do you see a stack trace with a line number?

The app (datafield) runs fine from Eclipse within Windows. The problem occurs with building. The first lines of the console output in Eclipse:

BUILD: C:\Program Files\Java\jdk-15\bin\java -Dfile.encoding=UTF-8 -Dapple.awt.UIElement=true -jar C:\Users\Joop\AppData\Roaming\Garmin\ConnectIQ\Sdks\connectiq-sdk-win-4.0.2-2021-05-13-9b3b7f19f\bin\monkeybrains.jar -o "Z:\Documents\Softwareontwikkeling\Garmin IQ ontwikkeling\Versies\DU8-10c0.iq" -e -w -y C:\CIQ-sdk\developer_key -r -f C:\Users\Joop\git\DR8-10c0\DR8-10c0\monkey.jungle

I can build the iq-file fine on another PC, so it seems to be related more to the environment then to the code. That's why I reinstalled Eclipse.

I have checked the paths in the build command; all files and directories are available.

I will reinstall the SDK manager. Maybe that that helps.

Maybe somwthing odd in your manifest.xml, or in the device files?

One of the "upcoming" devices from a while back?

I found it. For some reason building the iq-file on my server doesn't work anymore: "Z:\Documents\Softwareontwikkeling\Garmin IQ ontwikkeling\Versies\DU8-10c0.iq"

When I choose a location on this PC it builds fine. I haven't changed rights, I can delete existing iq-files in the specified directory on my server.

Thanks for helping.
