3750913 - Cannot perform runtime binding on a null reference

• Error seen after performing action which calls script:
• "Cannot perform runtime binding on a null reference".

SAP CPQ

When running actions which calls custom scripting, error is randomly thrown.

• The issue can be caused by usage of static variables within classes in IronPython scripts, combined with internal script caching, causes previously set values to persist across evaluations
• When a static variable depends on request-specific context (e.g. RequestContext.Url) and that context is null, null reference is accessed, leading to runtime binding error.

1. Identify class-level static variables in IronPython scripts that depend on request-specific context (e.g. RequestContext.Url)
2. Replace those static/class-level variables with a method that computes the value at runtime
3. Update all references to the former static variable to call the method instead.
