TypeError: weights.every is not a function

After the version was bumped from v2.0.3 to v2.1.2, I got the following error:

TypeError: weights.every is not a function
    at module.exports.drawWeights (smiles-drawer.min.js:56:216581)

    at Object.callback (bundle.js:2:11161)

The error disappeared after reverting to the previous version. From the traceback, the error should happen here:

smilesDrawer/src/SvgDrawer.js

Line 410 in 6676809

if (weights.every(w => w === 0)) {

Did you encounter this error in every browser or was it unique to Internet Explorer 11?

was it unique to Internet Explorer 11

My browser is Edge 108.0.1462.54.

You can take a look at my application.
v2.0.8

v2.1.2

I catch the error and make it fallback to pure texts, but the error message can still be shown in the console.

Can confirm. This project's own example file can recreate this:
https://github.com/reymond-group/smilesDrawer/blob/master/example/index_svg.html

Changing the line:

smilesDrawer/example/index_svg.html

Line 11 in 67bd106

To:
<script src="https://unpkg.com/smiles-drawer@2.0.3/dist/smiles-drawer.min.js"></script>

Works, while setting the version to 2.1.5 gives this error, as well as using the smiles-drawer currently in dist.
