Question:

In some cases where annotations exist with invalid formatting, Vault fails to export annotations. The user encounters the following error:

Answer:

This error is due to improper formatting with the value of line colors in multi-line drawings.

This has been fixed with Release Number 21R3.0.34.

In case a user encounters such an error, the workaround to rectify it is to either delete the annotations with multi-line drawings or update these drawings to only consist of a single line.

To update these drawings, first, delete the annotation with multiple lines and replace it with an annotation only consisting of a single line.

 
After doing so, the Export Annotations feature works as expected.
