I am on 13.5.6 and having the issue, "UND_ERR_REQ_CONTENT_LENGTH_MISMATCH" causing with "server action" while "revalidatingTag or revalidatingPath" . How to fix this ?

I have implemeted API routes and using that called backed server api using fetch api to get data now I want to revalidate that api using tag but getting above error.

Does anyone have any idea how to fix it?

Hey all, I was able to resole the UND_ERR_REQ_CONTENT_LENGTH_MISMATCH error by switching from fetch to axios.
