In OData, open collection properties are not supported

[ghost]

In sharepoint I have a column " Deck type" which accepts multiple choice values
To update the column value of a particular file I'm executing the below code

item = file.listItemAllFields
ctx.load(item)
ctx.execute_query()
multi_choice_value = FieldMultiChoiceValue(["Introduction"])
item.set_property("Deck_x0020_type",multi_choice_value)
item.update()
ctx.execute_query()

Upon executing this code I'm getting the below error

ClientRequestException: ('-1, Microsoft.SharePoint.Client.InvalidClientQueryException', "An open collection property 'Deck_x0020_type' was found. In OData, open collection properties are not supported."

Could anyone please tell the solution for this error?

Greetings,

thank you for reporting it, it confirmed to be a bug and could be reproduced in version 2.3.4 version and related with List Item update method when entity type is incorrectly getting determined.

Has been resolved in the latest (2.3.5) version
