When doing odata batch-requests in APP10, the response contains duplicate Content-Length headers. I’m using .net package Simple.OData.Client to call the API, and this client detects this as an error and throws an exception: “
The header 'Content-Length' was specified multiple times. Each header must appear only once in a batch part.
”
The actions i invoke in the batch:
PrePostSave(Init = true)<update shop-order-operation>
PrePostSave(Init = false)And it is the PrePostSave actions that return the duplicate Content-Length headers.
Has anyone also had this problem, and found a solution?
The response i get is:
