W4 lab. Second section - Creating & Setting up the Vector Database. Having issue with the terraform apply output.

 ![image](https://global.discourse-cdn.com/dlai/original/3X/c/8/c8eafdcf58077cb5848e64c7d97e399d2b3d43f8.png)  
Then, when I go to get the vector\_db\_host output:  
“Error: Output “vector\_db\_host” not found  
The output variable requested could not be found in the state file. If you recently added this to your configuration, be sure to run `terraform apply`, since the state won’t be updated with new output variables until that command is run.”  
Can’t continue past this point.

I can get the output vector\_db\_master\_username and password, but not the vector db host for some reason

Hello @MitchellYorkey  
As can be seen from the image below, `vector_db_host` is defined in the `output.tf` file. By default, these lines are commented out, and you are supposed to uncomment them in step 2.3. Therefore, in order to access this output, you need to complete step 2.3 and run `terraform init` and `terraform apply` command afterwards (step 2.4). Getting an error after `terraform apply` means these outputs are not processed correctly and won’t be available.

As for the error you added in the screenshot, did you change anything in the terraform files other than `main.tf` and `output.tf`?

I allowed the lab to expire and reset. On second attempt everything worked fine.  
Thank you
