was literally about to make a PR to fix the list model method. Looks like you beat me to it.

@ajithvcoder Hi, are you able to adapt this to work with this new PR for streaming in bedrock and also have no merge conflicts ?

[ajithvcoder]

@fm1320 it has been nearly 1.5 months so there are merge conflicts and will check the integration with this #314 . I fix everything and update this by Jan 23.

[lloydhamilton]

@ajithvcoder the tests i wrote in #314 are an adaptation of yours. So it should just work with your code.

[ajithvcoder]

@fm1320 the merge conflicts are fixed and #314 is already working fine as @lloydhamilton told.

[ajithvcoder]

@fm1320 could you review and merge ? else merge conflicts may occur again
