[Flight] Improve error message when it's not a real Error object (#28327
Browse files Browse the repository at this point in the history
)

Also deals with symbols. Alternative to #28312.

We currently always normalize rejections or thrown values into `Error`
objects. Partly because in prod it'll be an error object and you
shouldn't fork behavior on knowing the value outside a digest. We might
want to even make the message always opaque to avoid being tempted and
then discover in prod that it doesn't work.

However, we do include the message in DEV.

If this is a non-Error object we don't know what the properties mean.
Ofc, we don't want to include too much information in the rendered
string, so we use the general `describeObjectForErrorMessage` helper.
Unfortunately it's pretty conservative about emitting values so it's
likely to exclude any embedded string atm. Could potentially expand it a
bit.

We could in theory try to serialize as much as possible and re-throw the
actual object to allow for inspection to be expanded inside devtools
which is what I plan on for consoles, but since we're normalizing to an
Error this is in conflict with that approach.

DiffTrain build for commit a7144f2.
