Firebase functions: Error SignatureDoesNotMatch

[rubsilvah]

Hi, there!

I'm facing the same problem but I've already removed the content type while creating the signed URL.
The interesting fact is that this problem only happens suddenly a few days after the signed URL is created..

The code I'm following is the one below:
https://github.com/firebase/functions-samples/blob/master/generate-thumbnail/functions/index.js

Ps.: I have already followed the tips in the link below but the problem remains:
googleapis/google-cloud-node#1976

Thanks in advance!

Unless you changed the expiery date to a few days in the future (instead of 400 years in the future like the sample does) then I'm not sure what could trigger this. Maybe a but with the Cloud Storage service itself...

I am facing the similar problem.

I am facing this issue as well. Similar to @rubsilvah, my URL works for a few days, and then seems to expire with "SignatureDoesNotMatch" 403 response.

The URL seems valid too, and includes this query parameter: '...&Expires=16730323200&Signature=...'

For reference, here is a repo of relevant code:

Same issue reported here googleapis/google-cloud-node#1976
and here googleapis/nodejs-storage#144

Same problem here! Can't ship to production until this is solved...

The Firebase Admin SDK just wraps the Cloud Storage SDK, so you might be better off filing a report in the repo for the @google-cloud/storage module. https://github.com/googleapis/nodejs-storage/

Same here, the links work for a couple of days and then the following error happens.
"The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method."

Same here, the links work for a couple of days and then the following error happens.

Any solution? Same here, the links work for 7 days.

While the issues referenced above provide alternatives to getting a signed url on a google managed key, the tutorial should not be misleading and indicate that the url won't expire until the year 2500

This is also happening to me, works for a few days and stops. Any ideas?

Same here, it works for a week and then it doesnt.

This appears to be a known error and is linked to this issue googleapis/nodejs-storage#244

The eventual solution is to set your service account explicitly within your cloud functions googleapis/nodejs-storage#244 (comment)

I've just updated my code and will just have to wait and see if this solves it.
