AOSP repo sync command issue on Mac OS Catalina

[VCA VCA]

Based on the instruction, I tried 

"repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r40 --partial-clone "

And then, "repo sync".

However it failed many times as I re-try it many times, and the errors are:

RPC failed; HTTP 499 curl 16 Error in the HTTP2 framing layer

fatal: the remote end hung up unexpectedly

RPC failed; HTTP 502 curl 22 The requested URL returned error: 502

fatal: the remote end hung up unexpectedly

Does anyone know how we can make it?

Thanks a lot!

I'm just doing a regular master partial clone as well on Catalina and get that. My ubuntu machine has no issue syncing, so my guess is something in this new Catalina network stack isn't playing nice.
