[BUG] Not able to generate PDF reports

[tgeek77]

Describe the bug

When clicking on the Reporting -> Download PDF link from inside of the Opensearch Dashboard, I get the error "Download error There was an error generating this report."

To Reproduce

Steps to reproduce the behavior:

Setup:
Install Opensearch + Dashboard using the docker-compose file found in the setup instructions. We are only using the vanilla container images with no extra additions.

From the Web:

First, you must have data that spans at least 2-3 weeks. This is difficult to reproduct using the sample log data and we are not at liberty to share our data for an example.

Using Firefox (Chrome-based browsers have fewer errors)

1. Go to 'Dashboards -> [Choose your dashboard]'
2. View ~14 days of data
3. Click on 'Reporting -> Download PDF'
4. See the above error

Expected behavior
We should see a PDF report of the data on the screen

OpenSearch Version
This same issue has been seen in versions:
2.11.1 and 2.13.0

Dashboards Version
Same: 2.11.1 and 2.13.0

Plugins

We are not using any extra plugins in Opensearch/Dashboard or on the Browser

Screenshots

Console Errors:

As you can see, the issue seems to stem from an issue with reportsDashboards.plugin.js
