If you have installed collections of mods from other servers, not separately mods, but collections inside which this mod is included, then when joining a server with a clean mod, due to version and file mismatches, there may be such errors.

Also, some mods are not designed to work on servers, so this can cause errors. Carefully read the description, comments, discussions with the bugs.

Also, by this error, it can be judged that there are not enough parts of this mod on the server itself, if you use hosting service, then perhaps the mod was downloaded damaged, sometimes this even happens on the client side.
In this case, the mod needs to be removed and redownloaded
