Thank you for opening this issue, we will look into it.

[ThatCheck]

Same situation here. Unable to put in production now.

Do you have any ETA ?

[rolandstirnimann]

Do you have any ETA ?

Not really. As a workaround, I use the bastion via browser. However, it would be more comfortable to use it via Powershell CLI also for tunneling... Thank you.

[kaymaylove]

Same situation here. Maybe i can downgrade to a previous version like 2.53.0 where it was working 🤔

[HeyangQin]

Downgrading the bastion extension to 1.1.1 fixes the issue for me

az extension remove -n bastion
az extension add --name bastion --version 1.1.1

[labiol]

The same problem with "az network bastion tunnel". Tested on MacOs and LInux.

[rolandstirnimann]

@HeyangQin: Thanks for your hint. I have just downgraded the bastion extension and it works.

[luisbunuel]

Hi guys, still no new release to solve this issue?

[thecosmictrickster]

Piling on here, have the same error, @HeyangQin thanks for that tip, worked for me as well.

[kaymaylove]

I was able to do this and get it working:
pip install azure-cli==2.53.0

This didn't work for me :(

Downgrading the bastion extension to 1.1.1 fixes the issue for me

az extension remove -n bastion
az extension add --name bastion --version 1.1.1
