Question

When I try to update my Google App Engine app, I get the following error:

11:15 AM Rolling back the update.
Error 400: --- begin server output ---
Max error blob size is 10240 bytes.  Error blob "default" is 11875 bytes.
--- end server output ---

Any idea how to fix this?

Note:

I have deployed this app many times. I’m not sure what change I may have made to get this error.

Note 2:

I just ran appcfg.py with the –noisy option and I see the following generated line during the update attempt. I still don’t know how to fix this.

2012-11-15 12:04:37,477 INFO appcfg.py:1575 Adding errorblob default (11874 bytes, type=text/html) to batch.

Note 3:
It turned out to be the following lines in the app.yaml file:

error_handlers:
– file: server-error.html

Please see http://code.google.com/p/googleappengine/issues/detail?id=3759.

I can now update the app again after commenting those lines out.
