invalid input detected at marker (when installing EWC on Catalyst 9115axi-e Access Points)

[M007YN1AS]

I am trying install/activate the Embedded Wireless Controller on my C9115AXI-E Catalyst Access Points but I get the following error:" invalid input detected at ^marker " every time I give the following command: "AP1#ap-type ewc-ap tftp://192.168.1.25/ap1g7 tftp://192.168.1.25/C9800-AP-iosxe-wlc.bin. knowing that 192.168.1.25 is my tftp server address and in managed to change my AP address to 192.168.1.14

This is the methode I am trying to use to get it done.

any help would be much appreciated

Please note that if AP is already associated to WLC,
the new hostname will only reflect on WLC after AP
 dis-associates and rejoins.
AP1#capwap ap ip 192.168.1.14 255.255.255.0 192.168.1.1

TFTP server is located on an IP address 192.168.1.25. Unlike Mobility Express, it is required to specify 2 different images: one for the AP and one for the EWC. Conversion of the image will be done using the following command:

AP1#ap-type ewc-ap tftp://192.168.1.25/ap1g7 tftp://192.168.1.25/C9800-AP-iosxe-wlc.bin
Starting download eWLC image tftp://192.168.1.25/C9800-AP-iosxe-wlc.bin ...
