Tabular Editor - Set "Shared Expression" value from Tabular Editor CLI (with Azure Devops)

Question

I need to change the value of a parameter in a TOM. I am using Azure Devops with steps that include Tabular Editor CLI. I have written a one-line script that should be able to change the value of a Shared Expression. (Maybe a shared expression is read only?)

The script that will be executed

Model.Expressions["CustomerNameParameter"].Expression = "\"some value\" meta [IsParameterQuery=true, Type=\"Text\", IsParameterQueryRequired=true]";

I returns an error whenever Azure Devops tries to run it:

It cannot find the CustomerNameParameter in the model.

My build looks like this:

Your script looks good. Have you tried executing it within the Tabular Editor UI?

Perhaps the parameter is named differently in your model. You can use the following script in the CLI to output the list of parameters:

foreach(var expr in Model.Expressions) Info(expr.Name);

The result when executed in the CLI on the model shown in the screenshot above:
