Cloud compile warnings being treated as errors

I've been using electron successfully for several years. I can compile and flash locally in Visual Studio Code with all electron compatible toolchains but I can only cloud compile&flash 3.0.0 not 3.3.0 or 3.3.1 .
With 3.0.0 I get no cloud compile errors but with 3.3.0 or 3.3.1 I get a lot of warnings and then:

cc1plus: some warnings being treated as errors
make[2]: *** [../build/target/user/platform-10-msrc/UbiMesh.o] Error 1
make[2]: Leaving directory `/firmware/user'
make[1]: *** [user] Error 2

make: *** [modules/electron/user-part] Error 2

	at process.processTicksAndRejections (node:internal/process/task_queues:96:5)

I have a vague recollection that I can turn off warnings being treated as errors but I can't figure out how to do that. Any suggestions or hints?
Thanks, john
