Description of the problem including expected versus actual behavior:
When creating an index template with mappings that contain dynamic templates you will get the following server error:
Type: illegal_argument_exception Reason: "composable template [template_name] template after composition is invalid" CausedBy: "Type: illegal_argument_exception Reason: "invalid composite mappings for [template_name]" CausedBy: "Type: mapper_parsing_exception Reason: "Failed to parse mapping: A dynamic template must be defined with a name" CausedBy: "Type: mapper_parsing_exception Reason: "A dynamic template must be defined with a name""""
The client generates the request as follows:
{
"index_patterns": "pattern*",
"template": {
"mappings": {
"dynamic_templates": [
{
"key": "copy_to_all_fields",
"value": {
"match_mapping_type": "string",
"unmatch": "all_fields",
"mapping": {
"copy_to": "all_fields",
"type": "text"
}
}
}
],
...
Instead the client should generate the request as follows:
{
"index_patterns": "pattern*",
"template": {
"mappings": {
"dynamic_templates": [
{
"copy_to_all_fields": {
"match_mapping_type": "string",
"unmatch": "all_fields",
"mapping": {
"copy_to": "all_fields",
"type": "text"
}
}
}
],
...
Steps to reproduce:
- Define DynamicTemplates:
Dictionary<string, DynamicTemplate> DynamicTemplates; - Initialize DynamicTemplates:
var dynamicTemplate = DynamicTemplate.Mapping(new TextProperty() { CopyTo = "all_fields" });
dynamicTemplate.MatchMappingType = new[] { "string" };
dynamicTemplate.Unmatch = new[] { "all_fields" };
DynamicTemplates = new Dictionary<string, DynamicTemplate>
{
{ "copy_to_all_fields", dynamicTemplate }
};
- Start creating an index template with dynamic templates in mappings:
client.Indices.PutIndexTemplateAsync("template_name", pitr => pitr
.IndexPatterns(new[] { "pattern*" })
.Template(itm => itm
.Settings(s => s
...
)
.Mappings(tm => tm
.DynamicTemplates(DynamicTemplates)
...
)
)
)
Expected behavior
The index template should be successfully created with the correct dynamic templates in mappings.
