fetchPolicy
of QueryOptions
does not compatible with fetchPolicy of MutationOptions
. I fixed it by omitting the fetchPolicy
of QueryOptions
. Are there alternative ways to fix it?
@bakamitai456 I worked around it by doing this:
... (line 42)
case "mutation": {
const fetchPolicy = options?.fetchPolicy as MutationFetchPolicy;
const response = await client.mutate<R, V>({
mutation: doc,
variables,
...options,
fetchPolicy,
});
...
Not sure if that's more "elegant", but I prefer it to omitting QueryOptions
's fetchPolicy
. 😅
i dont think this is working with later versions of typescript. V does not satisfy OperationVariables
@beefancohen Did you find a workaround? I am having the same issue.

Thanks for this! What does

look like?
