Database queries not coming up

Hi, when I do a dynamic element on my page that is based on a SQL query (for example, a Bootstrap table generator or a dynamic dropdown), no data is populated either in Wappler or in the browser. However, the column names can be retrieved, just not the values.

Chrome shows me the following error - I am using a MySQL database. Is it a permissions/access problem? “Test connection” in Wappler shows no issues.

I followed the instructions to troubleshoot from this link ( and found the additional error details as follows:

My SQL database is hosted locally - see connection parameters:
MySQL connection details

I’ve matched this in the Wappler setup (tried both “localhost” and “” as host name and both have the same result):
