ElasticSearch is a powerful open-source search and analytics engine designed for horizontal scalability, reliability, and real-time search capabilities. It is commonly used for log and event data analysis, full-text search, and more. ElasticSearch allows you to store, search, and analyze large volumes of data quickly and in near real-time.
When working with ElasticSearch, you might encounter an error message like InvalidTypeNameException. This typically occurs when you attempt to create or update an index with a type name that does not adhere to ElasticSearch's naming conventions.
The error message might look something like this:
{
"error": "InvalidTypeNameException",
"reason": "Invalid type name [your_type_name]"
}
The InvalidTypeNameException is triggered when the type name provided in your request contains illegal characters or does not follow ElasticSearch's naming rules. Type names must be lowercase and cannot contain special characters or start with an underscore.
@, #, or $.To resolve the InvalidTypeNameException, follow these steps:
Ensure that your type name adheres to the following rules:
Update your request to use a valid type name. For example, if your original request was:
PUT /my_index/_mapping/InvalidTypeName
{
"properties": {
"field1": {
"type": "text"
}
}
}
Change it to:
PUT /my_index/_mapping/validtypename
{
"properties": {
"field1": {
"type": "text"
}
}
}
After making the changes, validate that your request is successful by checking the response from ElasticSearch. A successful response will not include the InvalidTypeNameException.
