Building docker firmeware esp32 error:unknown option to `s'

Question

I'm trying to build nodemcu firmware for esp32 using docker ce.

I'm getting this error message:

:~/nodemcu-firmware$ sudo docker run --rm -ti -v `pwd`:/opt/nodemcu-firmware marcelstoer/nodemcu-build build-esp32
sed: -e expression #1, char 99: unknown option to `s'

I don't know what I'm doing wrong...

Kind regards Arne

@Marcel Stör: You are right. This code solve my problem:

docker run --rm -ti -v `pwd`:/opt/nodemcu-firmware marcelstoer/nodemcu-build bash
git submodule update --init
exit
