TbaasClient

✓ from tencentcloud.tbaas.v20180416 import tbaas_client

✗ from tbaas import TbaasClient

Correct package path includes versioned API module

Initialize client with credentials and call a TBaaS API.

import os from tencentcloud.common import credential from tencentcloud.common.exception.tencent_cloud_sdk_exception import TencentCloudSDKException from tencentcloud.tbaas.v20180416 import tbaas_client, models try: cred = credential.Credential( os.environ.get("TENCENTCLOUD_SECRET_ID", ""), os.environ.get("TENCENTCLOUD_SECRET_KEY", "") ) client = tbaas_client.TbaasClient(cred, "ap-guangzhou") req = models.DescribeFabricBlockRequest() req.BlockNumber = 0 req.ChannelId = "mychannel" resp = client.DescribeFabricBlock(req) print(resp.to_json_string()) except TencentCloudSDKException as err: print(err)

Debug

Known issues

breakingThe old SDK (v2.x) used a different import structure (e.g., `from tencentcloud.tbaas.v20180416 import tbaas_client` vs `from tencentcloud.tbaas.v20180416.models import ...`). In v3, model classes must be imported from `models` submodule.

fix

Update imports: `from tencentcloud.tbaas.v20180416 import models` and use `models.DescribeFabricBlockRequest()`.

affects: <3.0.0

gotchaAll API operations require a correct region parameter. TBaaS supports limited regions (e.g., ap-guangzhou, ap-beijing). Using an unsupported region will cause a 'RegionUnavailable' error.

fix

Check available regions for TBaaS in Tencent Cloud documentation and specify a valid region when creating the client.

affects: all

gotchaThe `ChannelId` and `BlockNumber` parameters must exactly match the blockchain network configuration. For example, channel names are case-sensitive.

fix

Verify the exact channel ID and block number from your TBaaS console or network config.

affects: all

deprecatedSome older TBaaS API actions (like `InvokeChainMakerContract`) are deprecated in favor of newer Fabric-specific methods. Using deprecated endpoints may stop working without notice.

fix

Check the latest API documentation and migrate to supported actions like `DescribeFabricBlock` or `InvokeFabricContract`.

affects: >=3.0.0

Errors

Common errors & fixes

tencentcloud.common.exception.tencent_cloud_sdk_exception.TencentCloudSDKException: [TencentCloudSDKException] code: UnauthorizedOperation, message: You are not authorized to perform this action

Missing or invalid SecretId/SecretKey, or the account does not have permission for TBaaS operations.

fix

Ensure TENCENTCLOUD_SECRET_ID and TENCENTCLOUD_SECRET_KEY environment variables are set correctly, and that the account has been granted TBaaS access via CAM.

ModuleNotFoundError: No module named 'tencentcloud'

Missing required common package.

fix

Run: pip install tencentcloud-sdk-python-common

tencentcloud.common.exception.tencent_cloud_sdk_exception.TencentCloudSDKException: code: InvalidParameter, message: Parameter [ChannelId] is invalid

The channel name does not exist or is misspelled.

fix

Verify the exact channel ID from the TBaaS console. Note that channel names are case-sensitive.

AttributeError: module 'tencentcloud.tbaas.v20180416' has no attribute 'tbaas_client'

Attempted to import from wrong path (e.g., using `from tencentcloud.tbaas import tbaas_client`).

fix

Use correct import: `from tencentcloud.tbaas.v20180416 import tbaas_client`
