Might encounter an error when running the following commands:
```shell
cd packages/backend
yarn firebase:deploy
```
Error message:
```
⚠ functions: Upload Error: HTTP Error: 400, <?xml version='1.0' encoding='UTF-8'?><Error><Code>EntityTooLarge</Code><Message>Your proposed upload is larger than the maximum object size specified in your Policy Document.</Message><Details>Content-length exceeds upper bound on range</Details></Error>
```
Error Details: The uploaded Firebase function source code package is too large (exceeds 100MB).
Cause: After running `terraform` in the `backend/aws` folder, temporary files larger than 500MB are generated in `backend/aws`. The `backend/aws` folder is not needed for deploying Firebase functions.
**Solution**:
Modify the `firebase.json` file to exclude the `backend/aws` folder:
Before:
```json
"functions": {
"predeploy": "yarn --cwd \"$RESOURCE_DIR\" build",
"source": "."
}
```
After modification:
```json
"functions": {
"predeploy": "yarn --cwd \"$RESOURCE_DIR\" build",
"source": ".",
"ignore": [
"node_modules",
"aws"
]
}
```
- Note:
- Why add `node_modules`?
In the [firebase-tools source code](https://github.com/firebase/firebase-tools/blob/v13.12.0/src/deploy/functions/prepareFunctionsUpload.ts#L75):
```typescript
const ignore = config.ignore || ["node_modules", ".git"];
```
When the `ignore` node is not configured, `node_modules` is automatically ignored. However, when `ignore` is manually added, you must also manually add `node_modules` to the `ignore` list.
