Empty line added to Batch Request body

[ramanareddy438]

Hi Team,

I am using pyodata to batch upsert data into SuccessFactors OData API.

batch_req = sf_odata_service.create_batch()
change set = sf_odata_service.create_changeset()

cc_data = {
 "name_en_US": "Test",
 "description_en_US": "Test",
 "startDate": "/Date(-220898800000)/"
}

change_set.add_request(sf_odata_service.entity_sets.FOCostCenter.create_entity().set(**cc_data))

cc_data = {
 "name_en_US": "Dummy",
 "description_en_US": "Dummy",
 "startDate": "/Date(-220898800000)/"
}
change_set.add_request(sf_odata_service.entity_sets.FOCostCenter.create_entity().set(**cc_data))

batch_req.add_request(change_set)

batch_req.execute()

The above code is throwing Missing Boundary delimiter at line '4'.

I printed the body of the request.

I see an extra space added after the Content-Type. Not sure where the issue is from myside. Any help is greatly appreciated.

In the file pyodata/v2/service.py in line 46
lines.extend(('Content-Type: application/http ', 'Content-Transfer-Encoding:binary'))
There is an unnecessary space after the Content-Type header. This is I think why there is a space after the content type. When I change that it works for me.
In contrast to your case I use an API Gateway where validation fails.
