Discrepancy found in filing history

Hi,

I have found a discrepancy in filing history document returned by Companies House Beta API compared to Companies House Direct API:
Rolls Royce Group (04706930), the Incorporation filing history dated 21 Mar 2003 seems to point to entirely different document.
I have made the following call to CH Beta API:

Endpoint:

https://api.companieshouse.gov.uk/company/04706930/filing-history/MDE0ODIzNDI3MGFkaXF6a2N4

Response:

{
“description”: “incorporation-company”,
“type”: “NEWINC”,
“date”: “2003-03-21”,
“category”: “incorporation”,
“pages”: 88,
“paper_filed”: true,
“links”: {
“document_metadata”: “https://document-api.companieshouse.gov.uk/document/n_kVtVBDMmkPcb63ZO8GT_Exmz3Pg9A1qZ7fkZI55c0”,
“self”: “/company/04706930/filing-history/MDE0ODIzNDI3MGFkaXF6a2N4”
},
“transaction_id”: “MDE0ODIzNDI3MGFkaXF6a2N4”
}

The above result shows that the document contains 88 pages.
However, when we retrieved the document metadata, it returns the below result:

Endpoint:

https://document-api.companieshouse.gov.uk/document/n_kVtVBDMmkPcb63ZO8GT_Exmz3Pg9A1qZ7fkZI55c0

Response

{
“company_number”: “04706930”,
“barcode”: “D1Z1E7LO”,
“significant_date”: null,
“significant_date_type”: “”,
“category”: “miscellaneous”,
“pages”: 29,
“created_at”: “2015-07-03T08:57:07.215836996Z”,
“etag”: “”,
“links”: {
“self”: “https://document-api.companieshouse.gov.uk/document/n_kVtVBDMmkPcb63ZO8GT_Exmz3Pg9A1qZ7fkZI55c0”,
“document”: “https://document-api.companieshouse.gov.uk/document/n_kVtVBDMmkPcb63ZO8GT_Exmz3Pg9A1qZ7fkZI55c0/content
},
“resources”: {
“application/pdf”: {
“content_length”: 707188
}
}
}

As you can see, the above shows that the document has only 29 pages. When downloading the exact same filing history from CH direct, it returned the correct document with 88 pages.

This happens both in your API and your website: https://beta.companieshouse.gov.uk/company/04706930/filing-history

Direct link to the document: https://beta.companieshouse.gov.uk/company/04706930/filing-history/MDE0ODIzNDI3MGFkaXF6a2N4/document?format=pdf&download=0

Could you clarify why the CH beta returns a different document than CH Direct?
Which document contains the correct filing history?

Cheers,
Paco
