ElasticSearch Index a Document fails on existing index - php

Question

I am using ES php library. Here is what i have tried...
$params = [
'index' => 'tasks',
'body' => [
'settings' => [
'number_of_shards' => 3,
'number_of_replicas' => 2
],
'mappings' => [
'all' => [
'_source' => [
'enabled' => true
],
'properties' => [
'task' => [
'type' => 'string',
'analyzer' => 'standard'
],
'to' => [
'type' => 'string',
'analyzer' => 'standard'
],
'category' => [
'type' => 'integer',
'analyzer' => 'keyword'
]
]
]
]
]
];
// Create the index with mappings and settings now
$response = $client->indices()->create($params);
It returns success.
Now when i try to index a document...
$params = [
'index' => 'tasks',
'type' => 'all',
'id' => 'some_id',
'body' => [ 'task' => 'some test', 'to' => 'name', 'category' => 1]
];
$response = $client->index($params);
This throws error and does not work, however it works If i try this without creating index and mapping first.
Please suggest. Thanks

It's wrong to define analyzer in a field of type 'integer'.
Trying to create this mapping through Elasticsearch-PHP gives me a bad request:
... "reason":"Mapping definition for [category] has unsupported parameters: [analyzer : keyword]"}},"status":400}
Trying to create this mapping directly via PUT to ES gives me same error
I'm using ES version 2.2.0 and Elasticsearch-PHP 2.0
