Google BigQuery Encountering an 'invalidJobType' error when submitting a job in Google BigQuery.

The job type specified is invalid or unsupported.

Understanding Google BigQuery

Google BigQuery is a fully-managed, serverless data warehouse that enables scalable analysis over petabytes of data. It is part of the Google Cloud Platform and is designed to handle large-scale data analytics. Users can perform fast SQL queries using the processing power of Google's infrastructure.

Identifying the Symptom

When working with Google BigQuery, you might encounter an error message stating invalidJobType. This error typically occurs when you attempt to submit a job with an unsupported or incorrect job type.

What You Observe

Upon submitting a job, you receive an error message similar to the following:

{
"error": {
"code": 400,
"message": "invalidJobType",
"errors": [
{
"message": "invalidJobType",
"domain": "global",
"reason": "invalid"
}
],
"status": "INVALID_ARGUMENT"
}
}

Understanding the Issue

The invalidJobType error indicates that the job type specified in your request is not recognized by BigQuery. BigQuery supports several job types, including QUERY, LOAD, EXPORT, COPY, and others. If the job type does not match one of these, the system will return this error.

Common Causes

  • Typographical errors in the job type string.
  • Using a job type that is not supported by BigQuery.
  • Incorrect API usage or malformed requests.

Steps to Fix the Issue

To resolve the invalidJobType error, follow these steps:

Step 1: Verify the Job Type

Ensure that the job type specified in your request is correct. The supported job types are:

  • QUERY - For running SQL queries.
  • LOAD - For loading data into BigQuery.
  • EXPORT - For exporting data from BigQuery.
  • COPY - For copying data from one table to another.

Double-check your request to ensure the job type matches one of these options.

Step 2: Review API Documentation

Consult the BigQuery API documentation to understand the correct usage of job types and ensure your request is properly formatted.

Step 3: Correct the Request

If you find any discrepancies in your job type, correct them and resubmit your request. For example, if you intended to run a query, ensure your job type is set to QUERY:

{
"configuration": {
"query": {
"query": "SELECT * FROM my_dataset.my_table"
}
}
}
