What causes Rich Test Resuls to read different values that I what see in Chrome/Firefox inspect element?

Question

I have a critical issue with Google Rich Test Results:

Value in property "reviewCount" must be posivie The console shows this code:

<meta data-v-f499eefe="" itemprop="reviewCount" content="0" />

<meta data-v-f499eefe="" itemprop="ratingValue" content="5" />

and on the page I tesed, the code is the following:

<meta data-v-f499eefe="" itemprop="reviewCount" content="5">

<meta data-v-f499eefe="" itemprop="ratingValue" content="5">

I Tried checking with different browsers, but all showed me the correct value,

reviewCount" content="5"

I use a PWA as frontend.
