I'm trying to upload a custom shape library (XYZ-shape-library, based on example-shape-library from GitHub) to the Lucid Developer Portal for our enterprise instance. Using npx lucid-package bundle on Windows, but getting error on Developer portal while uploading zip package that i created using npx lucid-package@latest bundle ---
- Portal Error: "We could not upload that file. Please try again with a different .zip file.
Shape library error in GHD-shape-library: Unknown error: zip END header not found [<no file>]"
Tried:
- Running extension in localhost and then tested in Lucidcharts without any issues
- Tired edge and chrome browsers
- Re-bundling with lucid-package --clean.
- Manual package.zip with manifest.json + shapes.lcsz.
- Tried using another extension from Lucid’s Github samples
Questions:
- Known lucid-package or portal bug?
- Any upload workaround?
- Help troubleshooting
