What happened?

Variable replacement and cascaded variables are incompatible with backslashes \ in the variable name. This can impact more than just the variable with \ in the name as variable replacement may stop once it encounters an affected variable name.

Reproduction

Scenario 1:

1. Create a variable with \ in the name
2. Reference this variable name as the value for another variable
3. Check the variable preview or reference this variable in a write-host step

Scenario 2:

1. Create a variable with \ in the name
2. Reference this variable in a write-host step

Workaround

Use Octopus Parameters for variable names that contain a \ where possible: https://octopus.com/docs/deployments/custom-scripts/passing-parameters-to-scripts
