Cloudant sync android filtered pull

my database has a lot of documents, and each document has a field called doc_type, so i can filter it, but android is giving a error while trying to filter:

Map<String, String> parameters = new HashMap<String, String>();
parameters.put("doc_type", "doc_company");
PullFilter filter = new PullFilter("company/list", parameters);
Replicator replicator = ReplicatorBuilder.pull()
.from(uri).to(ds)
.filter(filter)
.build();


the error:

CouchException: error: Unknown error, reason: Unknown reason, statusCode: 404, msg: Object Not Found, cause: java.io.FileNotFoundException: https://(my_user_here).cloudant.com:443/db_404040/_changes?style=all_docs&feed=normal&filter=company/filter&doc_type=doc_company&limit=1000

i have the document with filter function:

{
"_id": "_design/company",
"_rev": "15-49d2081b2e3c35ae833617fd2356e6d3",
"views": {
"list": {
"map": "function (doc) {\n emit(doc);\n}"
},
"filter": {
"map": "function (doc, req) {\n emit(doc._id, 1);\n}"
}
},
"language": "javascript"
}


when i access


https://(my_user_here).cloudant.com:443/db_404040/_changes?style=all_docs&feed=normal&filter=company/filter&doc_type=doc_company&limit=1000


it give me this message:

{"error":"not_found","reason":"missing json key: filters"}
