BUG - Invalid boundary while parsing batch request (@sap-ux/ui5-middleware-fe-mockserver) with karma

[tobiasso85]

Error Invalid boundary while parsing batch request occurred when running ui5-middleware-fe-mockserver after compression task within karma-ui5

Features

@sap-ux/ui5-middleware-fe-mockserver

Description

when running the mockserver within karma-ui5, OData $batch requests fail with Invalid boundary while parsing batch request.
The batch request's body becomes {}

• ui5.yaml

...
server:
  customMiddleware:
    - name: sap-fe-mockserver
      afterMiddleware: compression
...

see related:

• UI5 Tooling Middleware behaves differently through karma-ui5 - request body not readable karma-ui5#410
• Limited functionality of custom middleware (Infinite loop when trying to handle HTTP request bodies) karma-ui5#344

Workaround

When changing

afterMiddleware: compression

to

beforeMiddleware: csp

it works.

Expectation

Documentation of the issue or fix

HI @tobiasso85 thanks for this, we actually had that in the readme before but i can't find it so we probably lost it during migration.
Will update this :)
