DO188 - not able to proceed with lab exercises

[DAmalan]

Hi, I am getting the following error in the lab environment for DO188.

Anyone else faced this issue and how to fix it?

DO188 with 4.12

Hello @DAmalan !

Thanks for reaching out !

It seems that your cluster is still not ready to accept any requests. When you start your labs - It is recommended to wait for 10-15 minutes so that the cluster gets ready to accept the requests and you can continue with your lab exercise.

Hi @Chetan_Tiwary_ 

Thanks for your response. Yes, I did wait for some time and then tried to run wait.sh at the utility server as outlined in your article however, I am still getting the following error. I have even deleted the lab and created a new lab but the issue still persists. It's complaining about some missing pieces (scripts) in the exercise library.

Hello @DAmalan !

looking at your screenshot - It seems you are not executing a valid lab start command. 

"Lab start exercise" is not a valid lab start script. It is just a syntax :

You should go to a guided exercise section and execute the lab start script mentioned over there.

Hi @Chetan_Tiwary_ 

Yes I am indeed following the guided exercise document.

lab action exercise is the syntex but the action should be either start or finish therefore I entered "lab start exercise". Kindly correct what's wrong with this command.

Hello @DAmalan !

The syntax mentioned in the section A.3 is for your information - a demo. 

That is not a guided exercise to perform. If you want to perform any lab or guided exercise in the course , go to the title "guided exercise" or "lab" like this

For example , if you are performing a guided exercise in chapter 02 section 2 : The lab start script is as shown below :

Thank you @Chetan_Tiwary_ Much appreciated.

lab start basics-creating is working.
