Form not allowing images

When I use the form to upload an image (to add to the map as an anonymous contributor) it does not succeed and I get an error message: Submission failed: {"status":500,"message":"Could not write form response. Kind: An error occurred when trying to execute a write operation: WriteError(WriteError { code: 16, codename: None, message: \"Error=16, Details='Response status code does not indicate success: RequestEntityTooLarge (413); Substatus: 0; ActivityId: d3e4543f-a70f-4768-bf39-43ddece87ecb; Reason: (Message: {\\\"Errors\\\":[\\\"Request size is too large\\\"]}\\r\\nActivityId: d3e4543f-a70f-4768-bf39-43ddece87ecb, Request URI: /apps/731c35df-1eba-40ee-b8b4-928c06404df1/services/100877df-6bf9-4a56-b5c9-8e76ab6b3c8f/partitions/35c81c46-38a8-4414-92d0-338384eccbe1/replicas/134224251090389831p/, RequestStats: Microsoft.Azure.Cosmos.Tracing.TraceData.ClientSideRequestStatisticsTraceDatum, SDK: Windows/10.0.20348 cosmos-netstandard-sdk/3.18.0);\", details: None }), labels: {}, source: None","backtrace":" 0: anyhow::error:: for anyhow::Error>::from\n at ./usr/local/cargo/registry/src/index.crates.io-1949cf8c6b5b557f/anyhow-1.0.100/src/backtrace.rs:27:14\n 1: as core::ops::trytrait::FromResidual>>::fromresidual\n at ./rustc/124cc92199ffa924f6b4c7cc819a85b65e0c3984/library/core/src/result.rs:2014:27\n 2: ::insertone::{{closure}}\n at ./build/mapmyx/core/src/data/data_model.rs:1811:22\n 3: as core::future::future::Future>::poll\n at
