# Error code: DATA_LOAD

This guide explains why you may experience a data loading error and how to solve it.

There are several ways and data file types in which you can import data into RelationalAI’s Relational Knowledge Graph Management System (RKGMS). See Data I/O for further details.

While importing data, several aspects require attention to successfully load certain data. Those related to how to access the data you want to import return a DATA_LOAD error if not properly configured. Check out the DATA_LOAD_CONFIG error if the issues are related to the loading configuration.

## Example: Wrong Path

Consider the following example:

def config[:path] = "azure://raidocs.blob.core.windows.net/csv-import/simple.jsonn"
def output = load_json[config]

The import option path is a string that specifies the location and name of the file you want to import from the cloud. Refer to Accessing the Cloud for further details on this aspect.

In the example above, the error is returned due to a typo in the URL string, i.e., jsonn instead of json.

The correct path returns:

// query

def config[:path] = "azure://raidocs.blob.core.windows.net/csv-import/simple.json"
def output = load_json[config]

## Example: Wrong Credentials

Consider the following example where you are trying to import private data:

module config
def path = "azure://myaccount.blob.core.windows.net/sascontainer/myfile.csv"

module integration
def provider = "azure"
def credentials = (:azure_sas_token, raw"sv=2014-02-14&sr=b&si=TestPolicy&sig=o%2B5%2F0C%2BLm7tWWftNKvQEGKHlSt%2Bfs8No7FZkUk5T%2Bv0%3D")
end
end

def output = load_csv[config]

In this case, the path to the data is correct but the credentials within the integration cloud parameter are not. This may happen because of a typo or because the provided credentials do not have enough permissions.

Note that the percent sign, %, is used for string interpolation within a Rel string. This means for URLs and cloud credentials you need to escape the character % with \% or declare the string as a raw strings (raw"...").
