Error] ERROR: The 'New-TFEWorkspace' command was found in the module 'tfe', but the module could not be loaded. For more information, run 'Import-Module tfe'.

Question

Hi Team,

I have installed tfe module using requirements.psd1 and given in host.json "managedDependency": {
"Enabled": true
},
In requirements.psd1 , it is as below

@{

For latest supported version, go to 'https://www.powershellgallery.com/packages/Az'.

To use the Az module in your function app, please uncomment the line below.

'Az' = '6.'
tfe = '1.'
Terraform = '1.*'
}

I am able to see my tfe module is installed in my function by running the command "get-module -listavailable -Name tfe"

After this, I am running few commands for creating New-TFEWorkspace.
Where as I am getting error when I trigger this function. Below is the error.

Hi @nagallibalu

Apologies for late response. Here is some information that should help you.

On examining the module definition, I can see that it checks to ensure that tar command is available for use.
To get around this error, I added the following in profile.ps1 file which creates a new alias for tar.exe and makes the tar command available within PowerShell script. Adding it to profile.ps1 ensures that it gets executed every "cold start" of the Function App.

#Define a new alias for tar  
New-Item -Path Alias:tar -Value C:\Windows\System32\tar.exe  

After making the change above and restarting Function App, the tfe module could be imported successfully.

Please 'Accept as answer' and ‘Upvote’ if it helped so that it can help others in the community looking for help on similar topics.
