Okay, i foudn out that the bug was introduced in the python extension 2018.8.0.

Just downgraded to 2018.7.0 and everything is working as expected.

d3r3kk · 2018-09-17T14:44:18Z

Thanks for the report @Brice187,

If you have the time, could you please try to install the latest development build of our extension and see if that fixes the issue for you? Let us know if that takes care of the issue.

(I suspect this is related to #2557)

Brice187 · 2018-09-18T04:51:09Z

@d3r3kk This bug is still present in 2018.9.0-alpha

Back to 2018.7.0...

DonJayamanne · 2018-10-01T22:40:03Z

@Brice187
Please ensure you are using the latest version of PTVSD in the docker container.
It looks like you don't have it at your end, the new version doesn't require the secret in the enable_attach method.

Once done, please get back to us.

Brice187 · 2018-10-07T11:46:58Z

After removing the secret ptvsd works as expected with 2018.8.0, thank you
