TS errors with ts-proto using grpc-web

[HypeillingerChillinger]

My goal is to communicate from the browser (Angular) to a C# backend. For that I'd like to use the grpc-web style using option

--ts_proto_opt=outputClientImpl=grpc-web

Using it produces Typescript errors in all fromPartial methods for all properties saying property x does not exist on I so I decided to remove the fromPartial methods since they are not that essential for me by using the option

--ts_proto_opt=outputPartialMethods=false

which resulted in a file where the fromPartial methods do not exist any more but they are still used in other places.

Can you give me advice on what to do to use grpc-web style or what I am doing wrong?

grpc-web option only

Created by using:

sudo protoc --ts_proto_opt=outputClientImpl=grpc-web --plugin=./node_modules/.bin/protoc-gen-ts_proto --ts_proto_out=. -I <myFolder> accounting.proto

For I it says:

Type 'I' does not satisfy the constraint '{ id?: number | undefined; valutaDate?: Date | undefined; remarks?: string | undefined; receiptHistoryId?: number | undefined; bookings?: { id?: number | undefined; paidFromAccount?: { ...; } | undefined; paidToAccount?: { ...; } | undefined; amount?: number | undefined; remarks?: string | undefined; bookingType?: B...'.
  Type 'unknown' is not assignable to type '{ id?: number | undefined; valutaDate?: Date | undefined; remarks?: string | undefined; receiptHistoryId?: number | undefined; bookings?: { id?: number | undefined; paidFromAccount?: { ...; } | undefined; paidToAccount?: { ...; } | undefined; amount?: number | undefined; remarks?: string | undefined; bookingType?: B...'.ts(2344)

Record is nested by the way

message Record{
   int64 id = 1;
   google.protobuf.Timestamp valutaDate = 2;
   string remarks = 3;
   int64 receiptHistoryId = 4;
   repeated Booking bookings = 5;
}

grpc-web option combined with the no partial option

Created by using:

sudo protoc --ts_proto_opt=outputClientImpl=grpc-web --ts_proto_opt=outputPartialMethods=false  --plugin=./node_modules/.bin/protoc-gen-ts_proto --ts_proto_out=. -I <myFolder> accounting.proto

Used versions

• protoc-3.15.8-linux-x86_64.zip
• ts-proto 1.115.5 (npm)

Workaround: I use

--ts_proto_opt=useExactTypes=false

@HypeillingerChillinger we've bumped the version of typescript; can you try the latest version of ts-proto and see if that fixes the error with useExactTypes? Thanks!
