Understanding the 'Did Not Find Expected - Indicator' Issue
The 'Did Not Find Expected - Indicator' error occurs in YAML files and is typically caused by having incorrect indentation, missing or misplaced hyphens, or a combination of both. YAML files are highly sensitive to indentation and formatting, so it is crucial to ensure that your file is correctly structured to avoid issues.
In the following sections, we will provide a step-by-step guide on how to identify and fix the 'Did Not Find Expected - Indicator' issue in your YAML file.
Step-by-Step Guide to Fixing the Issue
Step 1: Identify the Issue
First, identify the line number where the error is occurring. Most text editors and IDEs will provide this information when the error is detected.
Step 2: Check for Missing or Misplaced Hyphens
Examine the line with the error and the surrounding lines in your YAML file. Ensure that list items are correctly formatted with a hyphen - at the beginning of each item. For example:
fruits:

Step 3: Verify Indentation
Ensure that your indentation is consistent throughout the file. YAML files typically use two or four spaces for indentation. Make sure that your file follows a consistent indentation pattern.
Step 4: Validate Your YAML File
Use an online YAML validator, such as YAML Lint, to ensure that your file is correctly formatted. Paste your YAML content into the validator and fix any errors that are reported.
Step 5: Test Your Changes
After fixing the issue, test your changes in your application or environment to ensure that the issue is resolved.
