pdfMake create method Arguments are invalid - pdfmake

Question

I had been successfully generating a pdf using pdfmake I am now getting this error and I'm not sure what has changed. Even the simple examples are throwing errors.
const docDefinition = {
content: [
{
layout: 'lightHorizontalLines', // optional
table: {
// headers are automatically repeated if the table spans over multiple pages
// you can declare how many rows should be treated as headers
headerRows: 1,
widths: ['*', 'auto', 100, '*'],
body: [
['First', 'Second', 'Third', 'The last one'],
['Value 1', 'Value 2', 'Value 3', 'Value 4'],
[{ text: 'Bold value', bold: true }, 'Val 2', 'Val 3', 'Val 4']
]
}
}
]
};
const pdfDocGenerator = pdfMake.createPdf(docDefinition);
Results in:
//Argument type {content: {layout: string, table: {headerRows: number,
widths: (string | number)[], body: (string[] | ({text: string, bold:
boolean} | string)[])[]}}[]} is not assignable to parameter type
TDocumentDefinitions
However, if I use:
const docDefinition = {
content: 'Hello World'
};
const pdfDocGenerator = pdfMake.createPdf(docDefinition);
All seems well. I don't quite understand how any of the examples in the playground are working at this point. Any suggestions are greatly appreciated!

For reasons that I am unable to explain, changing my import to this resolved my issue.
const pdfMake = require('pdfmake/build/pdfmake');
const pdfFonts = require('pdfmake/build/vfs_fonts');
I am including pdfMake.vfs = pdfFonts.pdfMake.vfs; further down in my page when I am actually building out the pdf.
