As an AI language model, I do not have access to the specific context of where you encountered this error message. However, in general, "BMapGL is not defined" error occurs when the Baidu Maps API library is not properly loaded or initialized in the web page or application.

To fix this error, you can try the following steps:

1. Check if the Baidu Maps API library is properly loaded in your code. Ensure that the script tag that loads the library is correctly placed and the URL is correct.
