Description
with meilisearch:v1.15.2 the doc-scrapping is failing with error:

Docs-Scraper: https://gitdocs.test.com/gitdocs/chaoseng/prod/test-report.html 72 records)
JSONDecodeError while adding documents for https://gitdocs.test.com/gitdocs/testone/prod/tech-acceptance.html: Expecting value: line 1 column 1 (char 0)
First record: {'anchor': None, 'content': 'Overview', 'type': 'content', 'tags': [], 'url': '/gitdocs/testone/prod/tech-acceptance.html', 'url_without_variables': '/gitdocs/testone/prod/tech-acceptance.html', 'page_status': None, 'url_without_anchor': '/gitdocs/testone/prod/tech-acceptance.html', 'no_variables': 'True', 'objectID': '25e3aae1a36a3bdf95e8087dde245beff6aba378', 'page_rank': 0, 'level': 0, 'position': 1, 'hierarchy_lvl0': 'Check-in Open Systems :: Architecture / Design Guidelines :: Technical Acceptance Checklist', 'hierarchy_lvl1': 'Page title', 'hierarchy_lvl2': None, 'hierarchy_lvl3': None, 'hierarchy_lvl4': None, 'hierarchy_lvl5': None, 'hierarchy_lvl6': None, 'hierarchy_radio_lvl0': None, 'hierarchy_radio_lvl1': None}

the above error comes when i put the debugger in add_records method in meillisearch_helper.py.

Current version we have is 0.12.12

everything works well in getmeili/meilisearch:v1.7.6 instance

Expected behavior
doc-scrapping should pass
Current behavior
it is giving error
Screenshots or Logs
If applicable, add screenshots or logs to help explain your problem.

Environment (please complete the following information):

• OS: [e.g. Debian GNU/Linux]
• Meilisearch version: [e.g. v.1.15.2.]
• docs-scraper version: [e.g v. 0.12.12]

Start in meillisearch_helper.py at the add_records method, where the reported JSONDecodeError occurs, and reproduce the docs-scraper run against Meilisearch v1.15.2 and v1.7.6. Trace the document-adding response and compare the behavior; done means documentation scraping passes with docs-scraper 0.12.12 on v1.15.2.
