Unable to bind the http headers to an Http task with keys that have a : as a value. When we look at the exception stack (detailed below) and check line 264 of the code, it has a check that prevents values of http headers from having a colon in it (Code snippet also included below).
HTTP_TASK_REQUEST_HEADERS_INVALID = requestHeaders are invalid
Stack:
org.flowable.engine.common.api.FlowableException: requestHeaders are invalid
at org.flowable.http.impl.HttpActivityBehaviorImpl.setHeaders(HttpActivityBehaviorImpl.java:264) ~[flowable-http-6.1.2.jar:6.1.2]
Code from HttpActivityBehaviorImpl
protected void setHeaders(final HttpMessage base, final String headers) throws IOException {
try (BufferedReader reader = new BufferedReader(new StringReader(headers))) {
String line = reader.readLine();
while (line != null) {
String[] header = line.split(":");
if (header.length == 2) {
base.addHeader(header[0], header[1]);
line = reader.readLine();
} else {
throw new FlowableException(HTTP_TASK_REQUEST_HEADERS_INVALID);
}
}
}
}
