Hi all, I'm on an 18.3 cloud instance and have an issue with the document viewer component - I'm feeding it a document reference (note: I've verified the local!selectedDocument is of type document, the ri!uploaded docs is a list of integers) but it is returning an error as below:

Here's the text in case it isn't readable in the image:

Bad Request

Your browser sent a request that this server could not understand.

Additionally, a 400 Bad Request error was encountered while trying to use an ErrorDocument to handle the request.

and here is the code:

a!sideBySideLayout(
items: {
a!sideBySideItem(
item: a!dropdownField(
label: "Select document to view",
placeholderLabel: "Select document to view",
choiceLabels: a!foreach(todocument(ri!uploadedDocs),document(fv!item,"name")),
choiceValues: todocument(ri!uploadedDocs),
value: local!selectedDocument,
saveInto: local!selectedDocument
),
width: "MINIMIZE"
),
a!sideBySideItem(
item: a!documentViewerField(
label: "Document",
document: local!selectedDocument,
showWhen: not(isnull(local!selectedDocument))
)
)
}
)

Has anyone come across this or have any ideas?
