Issue with FormData Methods in Cloudflare Workers

I cannot directly pass FormData as the first parameter to c.newResponse. The TypeScript error indicates there's no overload that matches this call. The errors are as follows: 1. For the overload (data: Data | null, status?: StatusCode | undefined, headers?: HeaderRecord | undefined): Response, the error states: - Argument of type 'FormData' is not assignable to parameter of type 'Data | null'. - The type 'FormData' is missing several properties required by the type 'ReadableStream<any>', such as 'locked', 'cancel', 'getReader', 'pipeThrough', and three more properties. 2. For the overload (data: Data | null, init?: ResponseInit | undefined): Response, the same type mismatch issue arises, where 'FormData' is not considered assignable to 'Data | null'. Here is the NewResponse interface declaration for clarity:

interface NewResponse {
    (data: Data | null, status?: StatusCode, headers?: HeaderRecord): Response;
    (data: Data | null, init?: ResponseInit): Response;
}

interface NewResponse {
    (data: Data | null, status?: StatusCode, headers?: HeaderRecord): Response;
    (data: Data | null, init?: ResponseInit): Response;
}

My setup is shown below.

name = "cashplan-app-updates"
compatibility_date = "2023-12-01"
compatibility_flags = [ "nodejs_compat" ]

# [vars]
# MY_VAR = "my-variable"

# [[kv_namespaces]]
# binding = "MY_KV_NAMESPACE"
# id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

[[r2_buckets]]
binding = "R2"
bucket_name = "cashplan-app-updates"
preview_bucket_name = "preview-cashplan-app-updates"

# [[d1_databases]]
# binding = "DB"
# database_name = "my-database"
# database_id = ""

# [ai]
# binding = "AI"

name = "cashplan-app-updates"
compatibility_date = "2023-12-01"
compatibility_flags = [ "nodejs_compat" ]

# [vars]
# MY_VAR = "my-variable"

# [[kv_namespaces]]
# binding = "MY_KV_NAMESPACE"
# id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

[[r2_buckets]]
binding = "R2"
bucket_name = "cashplan-app-updates"
preview_bucket_name = "preview-cashplan-app-updates"

# [[d1_databases]]
