The error says that there is a problem with the path or with the file to which it writes, I checked the path many times, other functions for creating a file work and the converter from xls to pdf works the same, but why is there such an error in this library, who has encountered or knows how to solve, google but did not find the answer

html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title><%= title %></title>
</head>
<body style="font-family: Arial, 'Helvetica Neue', Helvetica, sans-serif; font-size:10px; padding:20px 40px; margin: 0; line-height:1.5;">
    
    <table cellspacing="0" cellpadding="0" width="100%">

        <tr>

            <% for( let i in column ){ %>
                <th><%- column[ i ] %></th>
            <% } %>
         
        </tr>

        <tr>

            <% for( let i in value ){ %>

                <% for( let v in value[ i ] ){ %>

                    <td><%- value[ i ][ v ] %></td>
                    
                <% } %>

            <% } %>

        </tr>

    </table>

</body>
</html>

The code

let params = {

        "title": fileName,
        "column": arrayColumn,
        "value": resultData["result"]

    }

    ejs.renderFile( manifest.file.templ.pdf, params, ( err, html ) => {

        if( err ) console.log( err );

        const options = { "format": "Letter"}

        console.log(`${timePath}${fileName}`);

        convert_HTML_PDF.create( html, options ).toFile( `${timePath}${fileName}`, (err, res) => {

            console.log(res);

            if( err ) console.log( err );

        })

    })

After checking the library apart from the main project it works. So there are some problems with the libraries in the main project or in the structure itself, but what can interfere?

Now a clean project with two libraries for building a pdf file gives the same error. The server did not reboot, it just began to give an error from scratch, did not change anything. I think it's already a matter of server settings, but what, what's stopping you?

Temporary solution to the problem
https://github.com/bazelbuild/rules_closure/issues/351
Run in the project: export OPENSSL_CONF=/dev/null
This method is so-so, at the moment I noticed that this setting is reset and periodically it needs to be rewritten. If someone finds a better way, please post.
