_next/data paths returning HTML for server-side props when used with OpenNext #1041
Description
Hi,
We're experiencing an issue where all _next/data JSON paths return HTML for requests from getServerSideProps. This breaks our state management workflow with zustand, as when the next page is shown it is unable to request the data from the store. I was able to instrument the application with OpenTelemetry, and it seems to be going right from getServerSideProps to render route (pages):
{
"default": {
"next.route": "/[checkoutId]/billing",
"next.span_name": "resolve page components",
"next.span_type": "NextNodeServer.findPageComponents"
}
}
{
"default": {
"next.route": "/[checkoutId]/billing",
"next.span_name": "getServerSideProps /[checkoutId]/billing",
"next.span_type": "Render.getServerSideProps"
}
}
{
"default": {
"next.route": "/[checkoutId]/billing",
"next.span_name": "render route (pages) /[checkoutId]/billing",
"next.span_type": "Render.renderDocument"
}
}
Our app is deployed on AWS via SSTv3. The same deployment directly via Amplify works without issues. Currently, this is blocking our migration to OpenNext/SST.
