I am creating a small azure function - HTTP trigger that is hosted on the Azure Cloud. Its main function is to simply receive post requests with a CSV file as payload.
However, some of the files that are posted are larger than 100mb, which results in the following exception:
"Exception while executing function -> Exception binding parameter 'req' -> The maximum message size quota for incoming messages (104857600) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.
I have tried to google my way and based on the azure function documentation from Microsoft: "functions-bindings-http-webhook"
it was stated that
The HTTP request length is limited to 100 MB (104,857,600 bytes), and the URL length is limited to 4 KB (4,096 bytes). These limits are specified by the httpRuntime element of the runtime's Web.config file.
Yet, I am unable to actually locate the Web.config within my solution, so I expect this is not really applicable or am I just totally off here?
The project is generated from Visual Studio with the following related dependencies and extensions:
Microsoft.Net.Sdk.Functions (1.0.24)
Azure Functions and Web jobs Tools (15.10.2046.0)
Are there any ways to increase the maximum message size limit for the received requests?
Does the App Service editor work for you?
However, I believe this approach is risky. In case of networking issues you can easily receive a timeout.
I would recommend that you upload your CSVs in a blob storage, and create a blob trigger for your function.
