[Go] Some models or embedders error out when invoked via runners in the Dev UI

[ssbushi]

Describe the bug
Some models / embedders error out when invoked from the Dev UI.

Eg: (in goolgeai):

gemini-1.5-flash, run fine

gemini-1.0-pro, errors out

Error running action key='/model/googleai/gemini-1.0-pro'.
TRPCClientError: Error running action key='/model/googleai/gemini-1.0-pro'.

Same for embedding-001 vs text-embedding-004

To Reproduce
Select embedding-001 in the embedder runner or gemini-1.0-pro in the model runner and invoke on a simple input, it should fail with an error like above.

Expected behavior
The action runs successfully without errors
