When calling a method that returns a ChromePdfRenderOptions object directly inside the initializer of a ChromePdfRenderer, IronPDF throws an exception at startup.

IronSoftware.Exceptions.IronSoftwareDeploymentException
HResult=0x80131500
Message=Error while deploying IronPdf Chrome renderer: 'The parameter is incorrect.'

HResult=0x80131500
Message=Error while deploying IronPdf Chrome renderer: 'The parameter is incorrect.'

Calling GetRendererOptions() (or any method returning rendering options) from within the ChromePdfRenderer object initializer can interrupt the renderer's initialization sequence. The object may not be fully constructed at the point the method runs, which causes the deployment exception.

Solution

Separate the method call from the renderer initialization. Call GetRendererOptions() first, then assign the result to RenderingOptions:

var options = GetRendererOptions();
var renderer = new ChromePdfRenderer { RenderingOptions = options };

var options = GetRendererOptions();
var renderer = new ChromePdfRenderer { RenderingOptions = options };

Dim options = GetRendererOptions()
Dim renderer As New ChromePdfRenderer With {.RenderingOptions = options}

Dim options = GetRendererOptions()
Dim renderer As New ChromePdfRenderer With {.RenderingOptions = options}

Alternatively, convert GetRendererOptions() to a static method if it has no instance-specific dependencies. Static methods are safe to call in object initializer contexts.
