ENOENT Error with puppeteer when creating .pdf

I am using puppeteer in my express server app to create a .pdf file from a html template. It works fine locally and throws this error when I upload the server app to railway. (from railway deploy log):

tempPath /app/create-invoice/temp/invoice_pi_3NERfyItN31KXN7T2Os3CniD.pdf
[Error: ENOENT: no such file or directory, open '/app/create-invoice/temp/invoice_pi_3NERfyItN31KXN7T2Os3CniD.pdf'] {
errno: -2,
code: 'ENOENT',
syscall: 'open',
path: '/app/create-invoice/temp/invoice_pi_3NERfyItN31KXN7T2Os3CniD.pdf'
}

tempPath /app/create-invoice/temp/invoice_pi_3NERfyItN31KXN7T2Os3CniD.pdf
[Error: ENOENT: no such file or directory, open '/app/create-invoice/temp/invoice_pi_3NERfyItN31KXN7T2Os3CniD.pdf'] {
errno: -2,
code: 'ENOENT',
syscall: 'open',
path: '/app/create-invoice/temp/invoice_pi_3NERfyItN31KXN7T2Os3CniD.pdf'
}

This is the code that I'm using in my node express server:

    getTemplateHtml().then(async (res) => {
    const template = hb.compile(res, { strict: true });
    const result = template(data);
    const html = result;
    const browser = await puppeteer.launch({
      headless: true,
      args: ['--no-sandbox', '--disable-setuid-sandbox'],
    });
    const page = await browser.newPage()
    // set the page content as the generated html by handlebars
    await page.setContent(html)
    //  use pdf function to generate the pdf
    const tempPath = path.join(__dirname, '.', 'temp', 'invoice_' + data.payment_intent + '.pdf')
    console.log('tempPath', tempPath)  
    await page.pdf({ path: tempPath, format: 'A4' })
    await browser.close();
    return true
      }).catch(err => {
        console.error(err)
      });
    }

    getTemplateHtml().then(async (res) => {
    const template = hb.compile(res, { strict: true });
    const result = template(data);
    const html = result;
    const browser = await puppeteer.launch({
      headless: true,
      args: ['--no-sandbox', '--disable-setuid-sandbox'],
    });
    const page = await browser.newPage()
    // set the page content as the generated html by handlebars
    await page.setContent(html)
    //  use pdf function to generate the pdf
    const tempPath = path.join(__dirname, '.', 'temp', 'invoice_' + data.payment_intent + '.pdf')
    console.log('tempPath', tempPath)  
    await page.pdf({ path: tempPath, format: 'A4' })
    await browser.close();
    return true
      }).catch(err => {
        console.error(err)
      });
    }

The console.log('tempPath', tempPath) is the first line in the error message. The next line (pdf creation) seems to create the error.:

await page.pdf({ path: tempPath, format: 'A4' })

await page.pdf({ path: tempPath, format: 'A4' })

Help would be much appreciated.

Strapi database reset after re-deploy

I'm curious if it's working as intended that the Postgres database deletes all custom data and resets to default whenever I deploy my newest Strapi backend from git. If so, is there a workaround to have the database persist?
