Getting Type 1 font support error message about non-existent Type 1 fonts

[Jay@Leidos]

I only have TrueType and OpenType fonts installed and I'm working with templates and documents created using only TrueType and OpenType fonts, but when I open files in InDesign, I get that big purple banner across the bottom warning me that my document contains anywhere from 1 to 30 or more Type 1 fonts and instructing me to replace them (without telling me which Type 1 fonts it says are in use).  I've gone through every paragraph style and character style in those documents to confirm that only TrueType and OpenType fonts were used and the Find/Replace font tool only shows the TrueType and OpenType fonts.  

I haven't used PostScript fonts in more than 15 years and none of the five computers I've used in the last 15 years (to create these very templates and documents) have ever had the older PostScript Type 1 fonts installed on them, so I'm baffled about what's causing those alerts.  

The only time I don't get those errors is when I open a new blank document.  Using those exact same TrueType and OpenType fonts in a new document does not generate errors about Type 1 fonts being used.  This only happens with legacy documents created using older versions of InDesign.

Any idea what's causing this and how to resolve this error message?

It's a known issue and is being worked on. You can safely ignore it in the meantime.

November 2023, Indesign version 18.3, I'm still getting this exact problem?

I'm sorry. Your comment is dated Jan 2022. But the issue has not been fixed because I am still getting the same alerts in the most up to date version?!?!

Is this an old file that would have used Type 1 fonts in the past? If you go to Type > Find/Replace Fonts, does the errant Type 1 appear in the list, and if so, can you "Find First" to see if it's used and where? Have you checked all your Paragraph and Character Styles to see if any still reference a Type 1 font? Even if they aren't being used, these Styles will still trigger the alert.

Thanks for your suggestions, Brad. The file is relatively new (created December 2023 and still going through the iterations with the client. No type 1 fonts have been used in the document. And typically, no notifications along the bottom of the screen. This morning I opened the file to receive the alert ... but the 'find first' dialogue box indicates '0' type 1 fonts. There are none lingering in the character/paragraph styles either. Stumped!

Export the file to IDML and open that. It may clean out any old information from the file. Otherwise, just ignore the alert.
