I'm going to merge in develop to retrigger the Netlify build so we can see the rendered page - I haven't seen it fail in initializing before, hopefully it was just a temporary issue?

[adeola-ak]

@rachhouse looks like the build isn't failing now, thanks

I can't find where I can update the tabs where it says Secure Your Api Data Source Connection String to be Data Source credential management instead

[rachhouse]

Hey @adeola-ak, you just need to update docs/docusarus/sidebars.js. Search for "Secure your GX API Data Source connection strings" in that file, and then you can update the label (which reflects the page title in the TOC) and the href so that it points to the new section.

[rachhouse]

Approved w/ comments (just a small text de-bolding change) so I don't hold you up on merging. Thanks!
