There are only a few similar questions for this and the solution in both of them is not working in my case. Here is a snippet of the code which is giving this error:

homepage.tsx file:

export const CTASection = () => {
  const {t, i18n} = useTranslation( {keyPrefix:("homepage.ctaSection")} )

  return (
    <StyledSection>
      <CTAContainer>
        <Header>{t('Header')}</Header>
        <Subtitle>
           Play and learn <i>risk-free</i>. Prove your knowledge, speculate and
          win!
        </Subtitle>
.....

my JSON file:

[
  {
    "homepage": {
      "ctaSection": {
        "header": "some thing"
      }
    }
  }
  
]

I am actually trying to use this content of the JSON file to be displayed on the homepage in the header section, and what I am actually getting is the error.
