The documented default is 1 MB per buffered response. Find the request URL in your network logs or SSR console, then decide whether SSR needs that data: raise the limit only as much as necessary, or disable transfer cache for a response needed only in the browser.
What NG02825 means
Angular’s error encyclopedia classifies NG02825 as a runtime error and titles it “Fetch response body exceeds the configured limit.” It occurs when Angular’s fetch backend buffers a response for an SSR request and the response body exceeds maxResponseBodySize. Angular documents a default limit of 1 MB for each buffered response body. Angular’s NG02825 documentation describes the trigger and default.

This is an SSR response-buffering limit, not a general browser download-size limit. It does not, by itself, identify which endpoint caused the error; that depends on the requests made by your application.
How to find the request that exceeded the limit
-
Read the error message for the configured limit, expressed in bytes.
#1 Best Overall
-
Check the server-side rendering console and request or network logs for the failing request URL around the time the error appears.
-
Trace that URL to the
HttpClientcall and establish whether the response is required to render the page on the server or only after the page reaches the browser.
The Angular diagnostic recommends using network logs or the SSR console to locate the request. The URL itself is application-specific, so the error code alone cannot reveal it. See Angular’s diagnostic guidance.
Choose a remedy based on where the data is needed
| Use case | Remedy | Scope and trade-off |
|---|---|---|
| SSR needs the response to render the page. | Increase maxResponseBodySize to accommodate the legitimate response. |
The setting is in bytes and applies globally to server-side HttpClient requests using the fetch backend. Larger limits allow larger bodies to be buffered, increasing memory use and denial-of-service risk. |
| The response is needed only in the browser. | Set transferCache: false on that request. |
This is a per-request option; it avoids caching that response for transfer from SSR to the client. |
| The response is a large download rather than data needed for server rendering. | Move the download outside SSR where practical. | This avoids making SSR buffer a response it does not need to render the page. |
Angular advises keeping the limit as small as the application allows and preferring to move large downloads outside server rendering. Angular’s NG02825 page documents both recommendations.
Rank #3
Raise the limit when SSR genuinely needs the response
Set maxResponseBodySize in the options passed to provideServerRendering. Angular’s example uses 5 MB, written as 5 * 1024 * 1024 bytes:
provideServerRendering(
{
maxResponseBodySize: 5 * 1024 * 1024, // 5MB
},
withRoutes(serverRoutes),
)Adapt the imports and route configuration to your application. The 5 MB value is an illustrative example, not a universal recommendation. Choose a limit based on the largest response SSR actually needs, and account for the fact that the setting applies globally to matching server-side requests. Angular documents the option and its trade-offs.

If SSR does not need a large response and the browser can fetch it after hydration, disable transfer cache for that request:
httpClient.get('/api/large-data', { transferCache: false });This is a request-level option. It does not raise the global body-size limit; it tells Angular not to transfer-cache that response. Angular’s diagnostic page shows this approach for client-only data.
Check the result
-
After changing the configuration or request, exercise the route through SSR and confirm the error no longer appears.
-
For an SSR-required response, verify that the configured byte limit covers the legitimate body without being larger than necessary.
-
For client-only data, confirm the browser loads it successfully without requiring it in the server-rendered response.
