i  deploying firestore
i  firestore: reading indexes from firestore.indexes.json...
i  cloud.firestore: checking firestore.rules for compilation errors...
✔  cloud.firestore: rules file firestore.rules compiled successfully
i  firestore: latest version of firestore.rules already up to date, skipping upload...
i  firestore: deploying indexes...
i  firestore: there are 1 indexes defined in your project that are not present in your firestore indexes file. To delete them, run this command with the --force flag.

Error: Request to https://firestore.googleapis.com/v1/projects/***/databases/(default)/collectionGroups/widgets/indexes had HTTP Error: 409, index already exists
Error: Process completed with exit code 1.

It’s true that the indexes already exist, but with v14.10.1, deployment completed successfully without any issues.

We have the same issue, maybe related to #7629?

Maybe we have to regenerate our local firestore.indexes.json now after that PR was included in 14.11.0

Hey folks, apologies for the issue here. I'm able to reproduce the error during deployments. To workaround the issue, please temporarily downgrade to firbease-tools v14.10.1

Let me discuss this issue with our engineering team.

Hi everyone, I've opened #8860 with a potential fix for this issue. It adjusts how __name__ fields are handled in indexes. Would appreciate if someone could review and test it!
